From johnsfolly at gmail.com Mon Jul 4 11:08:55 2011 From: johnsfolly at gmail.com (JohnD) Date: Mon, 4 Jul 2011 13:08:55 -0400 Subject: [Mg-t] TD Abandoned in Dodge City Message-ID: Ive gotten several emails asking what happened to my TD in Dodge City during the Rallye to Reno. The motor Manley Ford built ran like gangbusters all day long for 4 days, the last of which was 12 hours at 4000-4500 RPM with air temp at 106 deg. F. The car never exceeded 85 deg. C. water temperature and the B&G rear seal he put in deported itself exceptionally. Unfortunately, the last few very hot hours before Dodge City took its toll on the coil and then the SU fuel pump and then I developed an intermittent miss under load. After many hours in the parking lot of the Dodge House Hotel trying to diagnose that, and having checked or replaced EVERYTHING electrical, the TD rewarded me just before midnight with a metallic valve train sound that had not been there all day. Conferring with several others, and in view of the rally departure time just a few hours away, I decided to not risk pushing on over the Rockies and across the desert with that sound, and left the car in Dodge, completing the rally riding with others. So: good news/bad news. The TD came back to Michigan on a trailer. The metallic sopund?... a misaligned rocker cover touching one of the valve keepers. After checking for a broken valve spring and adjusting the valve lash in Dodge City, the cover got replaced a bit cock-eyed and tightened down. [Pause while I put a screwdriver through my left eye]. Good news: it was not a sticking tappet or push rod or valve guide. The motor ran great. Bad news: I still have the Dodge City miss and that will need to get sorted out. In the mean time, I have a Spridget race motor to assemble for MG Vintage Racers East Coast Focus Event at Lime Rock. Life remains an adventure!

If you can find some more of the spacers that keep the windshield frame from compressing in on the glass, that also would be a good addition. The wiper wire exits the same location. The later windshields had a couple of clips, that held the wire from the exit point, to the center wiper location.

Is this the first time you have experienced this in Texas?! A handful of crushed ice on top of each float bowl would have solved the problem. Usually you can get started if you don't ask for more than an idle. Then as cooler gas gets into the carbs, your running will even out. -John On Jul 17, 2011, at 10:04 PM, "oliver" wrote: > greetings from Dallas, where on a good evening the temperature drops to almost > 80. > > we were out in the car, about twilight. almost an hour later weather.com says > the ambient temperature is 90 > > we drove the car for about 10 - 15 minutes, then parked for about 10 - 15 > minutes. it would not start, although it seemed to catch for maybe one cycle > or less. > > fortunately, we were parked on a hill, and I was able to push start it. it > was very jerky for about 20 seconds, then ran just fine for the 15 minute > drive home. > > vapor lock? > ______________________________________________ > > Mg-t at autox.team.net > Donate: http://www.team.net/donate.html > Suggested annual donation $11.47 > Archive: http://www.team.net/archive > Forums: http://www.team.net/forums > Unsubscribe/Manage: http://autox.team.net/mailman/options/mg-t/johnsfolly at gmail.com From lawrie at britcars.com Sun Jul 17 21:05:15 2011 From: lawrie at britcars.com (Lawrie Alexander) Date: Sun, 17 Jul 2011 20:05:15 -0700 Subject: [Mg-t] trouble starting References: Message-ID: <697E34D74F4446D5865912846835BAE6@shop> Oliver, The new fuels which have ethanol in them vaporize more easily than gas used to.

This was diagnosed as fuel evaporating from the carburetor float bowl that is conveniently located directly above the exhaust manifold. The manifold heats up the float bowl and more or less boils away the gas. Once you start going again you have to get enough fresh gas through the float bowl to cool it enough to stop the boiling. That is why it stutters and runs poorly for a while. When I start the car after parking it the first thing I do is to let the fuel pump run until it stops ticking. This refills the empty float bowl. Usually this lets me get the car started, especially if I pull the choke out. The problem is that the car is running lean because of the gas boiling, so pulling the choke out helps. I also find it is necessary to run at well above idle, like in the range of 2000 rpm until things settle down. I run the car with no load, sit and let it run, until it is running normally, with the choke back in, and at normal idle, as I worry that running it while it is stuttering because of running lean could damage the engine if it is under load. This works for me when it is sunny and in the mid to upper 80's, but then again I am in upstate NY and not in the heat of Texas. I am hoping that the ultimate solution will be a heat shield that Brown and Gammons sells that protects the float bowl from the heat of the manifold. It is their part number GAC1036 "Heatshield TC, TD, TF". I got one, but have not gotten around to putting it in yet. Hope this all helps Roger in Poestenkill, NY Roger G.

As noted, vapor lock is the culprit. There are a number of fixes and some very simple. I installed a heat-sink at the suggestion of an engineer. My heat-sink installation is nothing fancy. The heat sinks are 3 wooden clothes pins clipped at the point where the fuel leaves the pump, another at the point where the fuel line enters each bowl. After 10 years I have never had a vapor lock problem. If nothing else, they are great conversation openers at a car show.

You will need to buy 4 metric studs, 10mm x 1.5 pitch x 1-1/2" long and 4 nuts for the studs from your local auto parts store, then you are good to go. We had actually tried a heat shield and wrapping the float bowls with insulating material but found no relief from the hot-start problem till we used the spacers. Apparently, it's the heat being transmitted directly from the hot engine into the carb bodies via the contact between the manifold and the carb flanges that causes the excessive heating of the fuel.

Thanks, Bob Grunau, Canada Roger, A check for $35, payable to Brian Sonner, mailed to 2700 Sleepy Hollow Court, Placerville, CA 95667-4222 will cover the cost of a pair of spacers, 4 gaskets and postage. You will need to buy 4 metric studs, 10mm x 1.5 pitch x 1-1/2" long and 4 nuts for the studs from your local auto parts store, then you are good to go. We had actually tried a heat shield and wrapping the float bowls with insulating material but found no relief from the hot-start problem till we used the spacers. Apparently, it's the heat being transmitted directly from the hot engine into the carb bodies via the contact between the manifold and the carb flanges that causes the excessive heating of the fuel. Thanks! Lawrie Hi Lawrie, How does one go about getting a set of spacers? They are a terrific idea. That along with the B&G heat shield should pretty much do the job. Roger Oliver, The new fuels which have ethanol in them vaporize more easily than gas used to. The heat of the engine is transmitted via the manifold studs directly into the carburetors so you end up trying to re-start the engine with fuel that's not mixing with the air the way it should. This problem has affected lots of folks in recent years. The cure I've found is to insulate the carbs from the manifold with spacers like the TF, MGA, MGB, etc. used. If you have 1-12" carbs you can use TF spacers and studs to replace the TD bolts (and new gaskets, of course). If you have 1-1/4" carbs, I have a local supplier of the correct size spacers which we had made up to solve this very problem on TCs and TDs.

First I will give a brief but complete story of the car's electrics and then describe what's happening recently. Maybe someone has an idea or suggestion. Car was purhased in 2003 and when received I found the battery to be installed backwards. I reversed it and never really had an issue in thousands of miles of driving over 8-9 years. The gauge always read discharging (to the right on a TF for some reason), but the battery never, ever went dead. I never worried about it and assumed that someday I would get ambitious and just reverse the leads. Last September, after a trip to the vintage races in Elkhart Lake the generator started making noises, but it was still doing its job. Not liking noises, I took the generator apart along with the generator from a TD "barn fresh" $500 parts car. I thought perhaps I could swap things and do a cheap fix, but the generator on the TF turned out to be toast. Kaput. Even though it had been generating, the armature was damaged and burned. The TD armature was actually better, but the whole works was overall pretty sad and no good for parts use. I had both generators rebuilt by Fondy Auto Electric, a company that has three shops in Wisconsin and seems to know its stuff. They told me that both armatures really needed to be "sent out and rewound" by another shop. I told them to do both for around $200 each. The TD generator is of the same family, but with a different suffix and has some kind of shield on the end that looks funky, but makes it not right for a TF. I put the TF generator on and all seemed fine. i even noticed that the generator bracket spacing needed to be tightened up. That may be why the old one was making noise as the loose spacing may have damaged the bearings a bit. I went on the Internet to figure out how to "polarize" the new generator. From the moment I did that, the car seemed to run better. For the last week or so, when I start the car, the red generator light has been staying lit for a time. The gauge needle also reads slight discharge. the car idles at about 9000-10,000 rpm and the fan belt is per the manual. The generator light will stay on (and the needle will go to discharge) for the first mile to mile and a half of driving. After that, the light will go out and rarely come on, even at a stop sign, unless tickover (I love that term) drops very low. The light being on has not caused any problem other than the light being on. This morning, the light did not go on when I started the car. this afternoon, when I came home, it did go on. Tonight I moved the car into my building and let it idle for a length of time that would be equal to driving it a mile and a half. The light came on and did not go out. I then revved the engine to higher rpms. Once I got up to 2500 rpm or so, the light immediately went out. I re-started and the same thing happened -- the light lit until I hit 2500 rpm. I would like to think this is not a generator problem. Fondy will probably redo the generator if it is, but I just hate taking it all off again if I don't have to.

John, I doubt seriously it's your generator(s). It's more than likely your voltage regulator...an easy way to check would be to swap out the TF generator with the TD one...if it's your voltage regulator it would give the same symptom with either generator. I highly recommend you have your voltage regulator modernized. Bob Jeffers (cc'd above) at http://wiltonae.com/home/index.aspx will take your existing regulator, gut it, install a transistorized circuit card, adjust it to the correct generator output and you'll never have to worry about it again. Best of all with the cover on the regulator looks stock and it won't cost but a fraction of the $200 you've got in each generator. I had mine done and I'm very pleased with it (http://wiltonae.com/articles_reviews/article_GettingAChargeOutOfIt/index.aspx), Best regards, Gene Gillam From lpalmer at roundaboutmanor.com Fri Jul 22 16:56:22 2011 From: lpalmer at roundaboutmanor.com (Lew Palmer) Date: Fri, 22 Jul 2011 17:56:22 -0500 Subject: [Mg-t] TF "Generator" Light In-Reply-To: <20110722.151522.22640.6@webmail12.vgs.untd.com> References: <20110722.151522.22640.6@webmail12.vgs.untd.com> Message-ID: <01f201cc48c2$93c5f0a0$bb51d1e0$@com> Before you attempt to adjust the regulator, first clean the points inside the regulator.

I don't foresee myself driving Madge at any time in the reasonable future, and she is just too nice to allow to sit and deteriorate. I will not be able to put my Comanche back together without more money than I presently have access to, so Madge Midget is looking for a home where she will be loved and appreciated as much as she has been with me. She is a 1972 RWA with a fresh 1275 and ribcase. The engine has about 4000 miles and the gearbox about 1000. No oil leaks anywhere. She has never been wrecked, but had a car roll into a front fender. It was replaced with a good one off my parts car, and the difference in paint color is barely noticeable if the light is right. She has rebuilt and freshly covered Bugeye seats, roll bar, 1962 chrome grille, and the early two piece tail lights. A new black top, still in the package, comes with her, as does a hood cover and slightly munched tonneau cover. Any extra parts I have lurking about will also be included. Pictures, pre tail light, are available on Just Ed's site. I am not able to take more at the present time. She is a solid, very driveable car that also looks good, despite a few rick chips. Make me a decent offer and she's yours to drive home. I would drive this car to the east coast and back without hesitation.
