I have a carbureted 4.3 liter Mercruiser. It starts fine runs great up to full throttle. But will not idle more than about 20 seconds then dies. If you try to start, have to apply full throttle to start (like the engine is flooded) When it starts to die if you apply throttle it will continue to run. As long as you keep the throttle above 1K it will continue to run fine, but bring it to idle and it stalls
I have replaced the spark plugs - plug wires - (cap does not look bad but have a replacement I will install today) I replaced the fuel filters - fuel pump - and a new carburetor that is supposed to have factory settings.
Yet the problem still persists. Can anyone offer advice??
