I have an 1980 Arctic Cat Jag. It would run and idle fine except for after it ran for a while (10-15 minutes) It would just stall out. Wait 5 minutes and it would be ready to go again. So I replace the fuel pump to fix this. Now with the new pump I can't get this thing to idle, it will run at high RPM. Or if I try to let it idle just before it dies I can choke it and it peps right back up.
Carb issue?? I tried messing with the air mix screw but don't really know what I'm doing, I set it to factory specs.
