The edelbrock performer on my bbo has had a rough go, and is now constantly clogging with stuff even though i have two fuel filters (one just out of tank and one after mech. fuel pump). I know the fuel tank is pretty dirty but there is no acess hole, and it is foamed and glassed into the bow of the boat. I am purchasing a rebuild kit this weekend as I have already gone through it multiple times with carb cleaner. Anyone got any suggestions on what else I should do? Maybe re-jet it? Thanks in advance.
