Nice to find a little jet site here! I've just been searching and reading but havent really found what I'm looking for. Any help would be greatly appreciated!
I'm running a 455 and just recently switched out my rochester carb for an Edelbrock 750 performer. The boat is idling great and running just ok at W.O.T. however I have absolutely no mid range, it just bogs sputters and almost dies. So I have to take it to wide open to get it to come out of the water. I have spent a few days fiddling with it and I'm still down about 10mph on the top end and still no mid.
I'm running the orange standard spring on it. Anybody running this carb on their 455? if so what spring combo are you running and how did you get it tuned in? I'm about ready to junk the the thing!
