Ok, now I have to admit I'm a bit baffled. Tonight, I went into the shop, adjusted the idle down on the Fastback, re-synced the carbs. I'm feeling a little good about it, it idles nice with just a very very slight roughness coming out of the extractor exhaust. According to my shop tachometer it's idling around 850 rpm. So I decide to check my advance again with my timing light (type with advance knob) and guess what... 26 degrees BTDC!!!! I pull off the vaccum line to the dist. and plug it. Immediatly the idle drops a couple hundred and idles silky smooth. Check the timing again, dead on at 7.5 degrees BTDC. Something is rotten in the state of New Mexico, folks. I couldn't possibly see how at dead stock idle, that this vaccum port should recieve any vaccum signal. So I took one of my "parts" 32 PDSIT's and examined the vaccum passage. It appears, as it should, that this vaccum port should recieve no vaccum until the throttle is taken to the off-idle position. I go about checking my freshly rebuilt carbs. Even when I rebuilt them, I noticed a very slight play in the throttle shafts, but I assumed that this would not affect anything too drastically. Was I wrong in my assumption? These shafts are not THAT loose at all. With very sensetive fingertips, you can just feel the play. Would it be a wise investment to have RIMCO go ahead and re-bush them? I'm lost here. I know in low speed situations, timing that is too far advanced can adversly affect these motors. To me that advance should not come in until you are applying throttle. Am I wrong in this assumption? HELP!!! Oh, I hear those 36mm Dells calling ;) Marc 1967 Fastback Is your boss reading your email? ....Probably Keep your messages private by using Lycos Mail.
