yes I know a lm1 would take all the guess work out of this, but unforutently I cant afford one of those at the moment. Tonight I decided to richen up my idle air bleeds from .072's to .070's and I started the engine and the choke was on letting it warm up and the choke opened but my fast idle was still on and it is popping thru the exhaust sounding a little lean and when I looked under the hood I noticed my passenger side hedders were glowing red. What the hell is up with that? I'm running 64 main jets at 4000 feet above sea level. Which is what quick fuel suggested running it. I read this was most likely un-burnt fuel burning in the exhaust and that when I loaded the engine it would go away. My timing is 15 degrees initial and 33 degrees total. I have never noticed this before because I haven't really messed with it after dark. What do I do about this?
