1974 454cid stock everything save for Accel HEI
I can't seem to get this thing to consistantly run well. I have the carb set but everytime I let it sit for a day or two then start it up, it sounds very rough (Kinda like it is missing on the right bank). I run it hard for awhile(hour?) and it starts to run smooth. plugs fouling? It is NOT running rich, lean if anything.
My mechanic(I am a newbie) tells me that it is the carb and it needs a rebuild. He also says I need a new fuel pump. I am not convinced.
Suggestions?
