I'm in the process if looking for a shop to do a little tweaking on my carb. It's still running a little rich and I just don't have the spare time right now to fiddle with it. So, in my search to find a shop that knows there way around a carbureted engine,alot harder than it should be, I talked to a local machine shop and they suggested that my problem was the fact my cam,236 @.050, is too big to run vacuum advance. I have never heard this before. Is there any truth to it?
