Ok, I've got a 1975 Mark Twain powerd by a Mercruser 888 (ford 302). Pre alpha drive. I have the engine out and and have problems wth the carb. The engine had sat for maby 8 years when I bought it and now it runs great (at times). I cleaned the thick gunk out of the carb and installed a renew kit and I can't get the adjustments right for it to run prpoperly. Its like its pumping way to much fuel w/no air. turning idle mixture screws have no effect whatsoever. If I shut the fuel off it runs great for an instant before the fuel runs out. I also have a concern about the carb itself. It is a Holley model 2300, 300 cfm (list number 6317). It doesn't have the "J" tube like the current marine carbs and I think I should just go ahead and replace it.
The question is should I send the carb out to be rebuilt by a pro or just replace it?
If I replace it would a 500 cfm 0r 600cfm 4 bbl be to much for this motor? The price of the new or refurbished 2bbl's are way higher than some 4bb's i have found.
