I don't boast about it, but I run a 151 GM 4 banger in my '81 CJ7.
The vacuum advance unit on the distributor is toast; it doesn't advance the spark anymore, probably a diaphragm problem. Also, the Rochester 2SE carb is old and no longer responds to adjustments.
NAPA or the cut rate parts places here want something like $375 for a new carb and nobody carries just the vacuum unit, they only sell complete distributors, for about $140. This is too rich for my blood, if you know what I mean.
I've tried Collins Brothers and I'll try Leon Rosser plus the local salvage yards in an effort to find used serviceable units.
Meanwhile, here's a few questions for the gurus on this forum:
1. A carb kit is only $25 but a buddy of mine indicates that would probablyu be money down the drain. He's gone that route and had to put on a new carb anyway. What experience or opinions do you guys have?
2. Anybody know where I could find a reference listing alternate carbs that might fit onto the intake manifold; this would give me more options in the used parts market.
3. Anybody have other suggestions (like other internet parts places) where I could go looking for these items?
Any assistance would be much appreciated. My internet sevice provider is having major problems now, so if you e-mail a response, please send it to:
