90 marathon bad fuel pump?
Just picked up my 1990 marathon, I knew it needed some work getting into it. Cleaned the carb new belt and oil injection line, when I drive it or have it on a stand it will take awhile to pick up and move then will gain speed like crazy then bog back down. I've found that if I feather the choke while I drive it it seems to run decent. Bad fuel pump? Or am I missing something?
