The new car has been hot rodded up a bit. Cam, bigger carbs and different pistons so it has a way different compression ratio and has been in this configuration for over ten years I believe. Was told it runs like the wind and came from a reliable and trust worthy person. Well I'm having problems with the car. Up to 2500 RPM, it runs great! When I can get it up to 3200 RPM it runs great again, it's the 2500 to 3200 range where I'm having problems.</p></div><div><p class="MsoNormal"> It feels like it's starving for fuel, or it has too much fuel, it hesitates, feels like it's not running on all cylinders, and generally like a bucking bronco, but then at 3200 or so, she smooths right out and flies!</p></div><div><p class="MsoNormal"> I was told the carbs were set up a little rich. I leaned them out one flat at a time and no difference until they got too lean and wouldn't run well at all. So I took them back to original setting positions. </p></div><div><p class="MsoNormal"> I've checked all gaps, they're all right. Pulled plugs when getting home and they are all fine, a little brown and all even looking. New condenser, new coil, changed to new plugs, I have not checked the timing yet, but with the way it runs below 2500 and above 3000, it seems to be just fine.</p></div><div><p class="MsoNormal"> I am getting the car up in the air Monday as I have new tires to replace the old ones and will do a static timing check at that time. My old four cylinder was a breeze to set up and ran smooth through all revs. What am I missing with an engine set up like an M? Why would things go south between 2500 and 3000 and run fine below and above?</p></div><div><p class="MsoNormal"> All suggestions are welcome and I do have a new fuel pump on order, so fire away. I've been doing things one step at a time to not introduce new problems, but this is the only problem that is consistent.</p></div><div><p class="MsoNormal"> Thanks,</p></div><div><p class="MsoNormal">Steven Kingsbury</p></div><div><p class="MsoNormal"> </p></div><p class="MsoNormal" style="margin-bottom: 12.0pt;" data-mce-style="margin-bottom: 12.0pt;"> </p><pre>_______________________________________________</pre><pre>Support <a href="http://Team.Net" data-mce-href="http://Team.Net">Team.Net</a> <a href="http://www.team.net/donate.html" data-mce-href="http://www.team.net/donate.html">http://www.team.net/donate.html</a></pre><pre>Suggested annual donation $12.75</pre><pre> </pre><pre>Archive: <a href="http://www.team.net/pipermail/healeys" data-mce-href="http://www.team.net/pipermail/healeys">http://www.team.net/pipermail/healeys</a> <a href="http://autox.team.net/archive" data-mce-href="http://autox.team.net/archive">http://autox.team.net/archive</a></pre><pre> </pre><pre><a href="mailto:Healeys@autox.team.net" data-mce-href="mailto:Healeys@autox.team.net">Healeys@autox.team.net</a></pre><pre><a href="http://autox.team.net/mailman/listinfo/healeys" data-mce-href="http://autox.team.net/mailman/listinfo/healeys">http://autox.team.net/mailman/listinfo/healeys</a></pre><pre> </pre><pre>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/coudesluijs@chello.nl" data-mce-href="http://autox.team.net/mailman/options/healeys/coudesluijs@chello.nl">http://autox.team.net/mailman/options/healeys/coudesluijs@chello.nl</a></pre><pre> </pre></blockquote><div id="DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><p class="MsoNormal"> </p><table class="MsoNormalTable" border="1" cellspacing="3" cellpadding="0" style="border: none; border-top: solid #D3D4DE 1.0pt;" data-mce-style="border: none; border-top: solid #D3D4DE 1.0pt;"><tbody><tr><td width="55" style="width: 41.25pt; border: none; padding: 13.5pt .75pt .75pt .75pt;" data-mce-style="width: 41.25pt; border: none; padding: 13.5pt .75pt .75pt .75pt;"><p class="MsoNormal"><a href="http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient" data-mce-href="http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient"><span style="text-decoration: none;" data-mce-style="text-decoration: none;"><img border="0" width="46" height="29" style="width: .4791in; height: .3055in;" id="_x0000_i1025" src="https://ipmcdn.avast.com/images/icons/icon-envelope-tick-green-avg-v1.png" data-mce-src="https://ipmcdn.avast.com/images/icons/icon-envelope-tick-green-avg-v1.png" data-mce-style="width: .4791in; height: .3055in;"></span></a></p></td><td width="470" style="width: 352.5pt; border: none; padding: 12.75pt .75pt .75pt .75pt;" data-mce-style="width: 352.5pt; border: none; padding: 12.75pt .75pt .75pt .75pt;"><p class="MsoNormal" style="line-height: 13.5pt;" data-mce-style="line-height: 13.5pt;"><span style="font-size: 10.0pt; font-family: 'Arial',sans-serif; color: #41424e;" data-mce-style="font-size: 10.0pt; font-family: 'Arial',sans-serif; color: #41424e;">Virusvrij. <a href="http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient" data-mce-href="http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient"><span style="color: #4453ea;" data-mce-style="color: #4453ea;">www.avg.com</span></a> </span></p></td></tr></tbody></table><p class="MsoNormal"> </p></div></div><style class="existing-message-styles" type="text/css">.msg-quote p.MsoNormal, li.MsoNormal, div.MsoNormal {margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;}
