I inherited a 1983 Lund with a 112 Johnson SPL on it. I can pump the bulb and start it and it'll run for about a minute and then die. If I pump the bulb it'll keep running, what do I need to check or replace to resolve this problem? I have so far changed the fuel filter and put on a new bulb. I also checked for an anti-siphon valve and didn't have one and checked the tank vent and that seemed fine. I can take it out to the lake and it'll run fine for a bit, then not run. Is it the fuel pump or should I be looking at something else?
