Good compression 120/119/120 and spark good spark on all three cylinders,
Problem: No sign that the bottom spark plug is burning; therefore engine is working with two cylinders only.
Back in January a mechanic at the NYC Boat show informed me that it has to be fuel related; perhaps the carburetor. Well I just finished cleaning and re-building the bottom carburetor. Checked again for signs of burning; The bottom spark plug still no sign of burning,
can not figure out why there is no ignition/fire on this cylinder.
