Holley Carb Issues.... NEED HELP
Motor is a 454 Big BLock with a Holley 750
Stock Lower end, Stock heads, mild cam, Edelbrock rpm intake, headers, HEI Idle is perfect Free Rev sounds good When put in gear it idles fine and if you ease into the trottle everything is OK PROBLEM: When in gear and mash the trottle it hesitates then takes off and sounds great but as soon as you get out of the gas it falls on its face and dies I have made sure the floats are adjusted to were fuel barely comes out of the sight plug at idle I put two carbs on and am still having the problem, although it is not as severe with this 750. IS it the carb,? Any help is appriciated, she is going to the Mud Run this weekend.......... MAybe?? Thanks guys
