Re: carburetor jets
Eric, I ran the stock factory spec. 4346 carb except for the jetting. If memory serves me correctly, the PVs were both 6.5 but don't quote me on that. I don't know what the vacuum idle was. I couldn't have asked for the carb to work any better. I have a 4346 done the same way on our L78 engine and it works the same way. Having carbs that were already built for the application probably helped a lot as far as tuning went. A friend of mine does some racing and he gets into modifying the restrictors in the body of the carb, stuff that I know nothing about. When he is done, it is surprising at how well a carb can run, and how far off most carbs are when he first starts on them.
