Thread: Edelbrock carb problems

Well, 750 is a little big for a 350, unless the engine is bumped up a bit HP wise, 600 would probably work better. But that shouldn't be what you are describing. Is the accelerator pump spraying as it should, what hole is it in? Has this carb ever worked ok with this combination? How about timing, is your vacuum advance working? Have you tried going up or down on initial timing?

It could be that 750 cfms is just dumping too much air into the engine for it to accept, when you get your foot into it. What all has been done to the motor? What intake are youi running? Might check your float level, could be too low.
