The car runs fine except it is getting 10 mpg (terrible economy) and stumbles on acelleration in 4th gear.
It seems worse when the engine is cold, and it takes a while to warm up.
I have replaced the Holly carb that the engine came with, with an eledbrock preformer and nothing changed. I have tried changing the advance, adjusting the carb. What next?
have the same problem?
