Ya, well I guess the problem I have is starting when warmed up, seems like an old tractor trying to start, slow to start you can say.. when its cold it fires right up. also, when you put your foot into it, would like to hear more secondarys and that deep growl kicking in the 4bbl. the teck from holley says the carb i have and the setup should work good. maybe check to see if there is a spacer plate under carb. dont remember. have to look. was told fuel may be getting too hot and not firing up good.. been looking for a good speed shop in my area but not too much success yet.. thanks for your input..
