Bad rusty gas tank replaced and several carb rebuilds has landed in several carbs meeting the trash. I did however find that the motor (348) could run nice occasionally. There is hope. I found the most recent Holley carb to run the best but was actually crumbly. Yes it has mega cracks and would run ok sometimes but small pieces would crumble off here and there. WTF? So trash! Going to buy a new Holley today but may try to run my truck carb first as it has been a real good carb and starts and run great every time. It is on a 406 small block though and I hate to take a good running motor apart. What to do? It will need a carb eventually anyway so run the truck carb first for a baseline and then run the new one that of course will need adjustments and blah blah to get it right? I have been struggling with this sucker for so long it has me frandustiggled! I want to drive this beast! I am about to spring for some fuel injection! I have seen what I believe to be a vacuum leak in all the carbs I have tried as the idle mixture needles only make it run ok when they are turned in all the way. This should kill the motor altogether but nope. Runs great that way. Futha what? Baffled! Intake leak?
