The first thing I do is determine whether its electrical or fuel. With fuel in the bowls, it tends to point to electrical although I also check the carb dampers and that the pistons can move up and down (not stuck). On the electrical side, I pull out a spark plug to check appearance and then with it connected to the ignition lead, place it on the block and check for a visible spark when cranking the engine.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Now to add to this, a short story on my last issue of this nature – I was having some intermittent and very short durations of power loss when I started driving my 64B this spring which I at first thought might be moisture in the fuel…until it completely died on the drive home one day (after I ignored the problem for several days). I coasted into a nearby Wendys parking lot and determined there was no spark so I started checking connections, particularly the condenser to points connection (insure tightness, proper insulation with the plastic washer). Turns out the nut was slightly loose so I tightened it. Car started right up and I drove home. But the intermittent cutting out started to return again (maybe a few 1-2 second incidents over several miles). So I decided to replace the points and condenser the next weekend and that was when I discovered the real problem. On the points terminal that the condenser attaches to, there is another cloth insulated wire that attached to a plastic terminal on the distributer (part #16 - <a href="http://www.mossmotors.com/Shop/ViewProducts.aspx?PlateIndexID=29062">http://www.mossmotors.com/Shop/ViewProducts.aspx?PlateIndexID=29062</a> ). The wire had started rotting away to the point that it was down to a few copper strands (but unseen inside the cloth insulation)and it disintegrated during the points removal. Fortunately, I had a spare distributer that I could get a replacement part off and that solved the issue. Car has been running great now with about 500 miles or so of error free operation.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Other suspects would be the condenser or possible the ignition coil – I have had these fail in the past. And as far as cam flat spots – I have had that issue too about 30 years ago. However, that did not stop the car from running – it just idled rough and suffered a lack of power (but not a loss of power). You would know when doing the routine valve adjustments as you will not see much up/down movement of the valves.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>David Councill<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>64 MGB<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>67 MGBGT<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>72 MGB<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> Mgs [mailto:mgs-bounces@autox.team.net] <b>On Behalf Of </b>Robert J.

I found a gas station and refueled (the gas had alcohol and I usually run non-alcohol gas). About 30 miles later, the car started to lose power and then quit. Figured it was a clogged fuel line, but fuel was pumping out of the fuel line at the rear carb and there was gas in both float bowls. Cleaned out both float bowls. Had spark from the coil and to all plugs. Had just replaced spark plugs and gapped them to spec two days previously. Regapped points (1 year old 25D distributor). Nothing. Sprayed starting fluid in the carbs. Nothing. Locals towed me back to town. Locals played with wires under the bonnet at the coil as I politely batted them away. As a last ditch effort, I advanced the timing and it caught at high revs! Drove a few miles, but lost power as I accelerated and stopped. Stripped and reattached coil wire to harness. Started, drove a couple of miles, faded, and stopped. Towed it home. At home, it started reluctantly. It drove for a couple of miles and it faded and quit. Gas in rear carb float bowl but no gas at the front carb float bowl. Blew air from fuel pump back to gas tank with audible air flow at the gas tank. Replaced the float bowl needle and seat at the front carb. Fuel pumping nicely at both front and rear carbs. Have spark from the coil and to all plugs. Static timed. Nothing, doesn't even try to catch. I do not have a fuel filter other than stock sleeve in the fuel pump. No odd sounds. I am stupefied ( except for the possibility of clogged jets, but if so why wouldn’t it start with starter fluid). If it is the coil or condensor, why am I getting spark? Why would advancing the timing get it to go at such high revs that one time, but normal timing gives you nothing at all, not even a spit? Do I have a cam flat spot problem? How have I angered the British engineering gods? Any hints or diagnostic suggestions?<o:p></o:p></p><div><p class=MsoNormal>-- <br><br><o:p></o:p></p><p class=MsoNormal style='margin-bottom:12.0pt'>Robert Guinness<o:p></o:p></p></div></div></body></html>
