1987 150...i put a new crank shaft in...i finally get it started and it runs a little rought...its idling at 2200..i know too high but i can fix that..i swap out the vro for old style pumps with pre mix...after idling for 5 minutes i shut it down but it will not restart....it just cranks..bulb is firm but not super hard...fuel drips from carbs when i squeeze bulb...why wont it restart? how do i troubleshoot this?
