Merc 50 1984

[spareparts]

That's a classic 50? 4 cylinder? Sorry the previous post I made was about it being a 3 cylinder. Those engines are pretty basic. Look into the carbs and sqeeze the primer bulb, if you have gas coming out of the carb, the needle needs cleaning/replacing or their float is bad. Running rich(excess fuel) will cause the plugs to be black, running real rich(rolling fuel) will clean the plugs off, they will look wet. Like I said in teh other post have the carbs gone thru. Decarb the engine, and rebuild teh fuel pump, you should be goof to go
