That's what I was wondering. Amazing how all this works out. I still havent had a chance to fix the vacuum leak but once I get that fixed i'll take another stab at the idle screws and the carb sync. Seeing as I only shimmed the original needles, I'll have to keep in mind what they're set at. With infared thermometers, even if you got it at the same temp, how would you know it's not overall rich or overall lean? Besides seeing if it runs crappy.
