I ran some butane around the intake and carb and found the back of the carb was leaking. We had it mostly off and Christian noted that the brake booster line was finger tight. We took it off the rest of the way and also found that there was silicone used instead of a gasket under the tin plate that Pontiac uses on top of the intake before the main gasket. I don't remember doing that but it could have been a " if this works for now, great and I'll fix it right later " . So for today we took a Wheaties box and I made a gasket out of that and if it works for now, great and I'll fix it right later We'll it did help quite a bit, still have a low shaky vacuum but it could maybe be cam related? It does have a thumpity- thump- potato- potato sounding idle but still is lacking the pull I thought it had in 3rd and 4th gear. I'll get a carb kit coming for it, and maybe my exhaust is choking it out as well. I should order some Ram Air IV manifolds and larger exhaust but sometimes I get tired of spending money.
