Have a 83 50Hp merc after getting the carb issues sorted out the engine runs pretty good actually
Problem is the compression is low. Between 85 and 90psi on all cylinders
Think decarbing the engine might help the compression?
Im almost positive it has never been done and the PO had the idle needles way rich trying to compensate for the messed up carbs. No idea how long it was like that before I got it but its all fixed and adjusted properly by a dealer. I hope!
If decarbing will not do it I guess i'll need to re ring it. From looking at it, it seems like it would be pretty easy as long as nothing else is bad.
The engine is actually in great shape with New stator, Switch box, new seals in LU, Rebuilt carbs with new floats, Timed and Linc and sync, New wiring harness, New prop.
Also if this is going to run over 500/600 bucks I think I would be better off finding a different engine?
Anyone care offer your advice on this situation
