I have an 1971 4 cyl 65 hp. I have problems with the engine at idle. I try to troll around and the engine will idle around for about 20-30 minutes then the motor loads up and dies, the engie will start back up and run the fast idle for a second. Then shift into gear and open the throtle up the engine runs just fine. Then engine will also idle just fine fine when the engine is under no load at all. I have rebuit the fuel pump and replaced the fuel line, have also replaced the squeese ball. What do you guys would think the problem is?
