Hoping someone can suggest what could be wrong.
Motor has been running fine but when we finished last trip whilst trying to trailer engine would not idle and would keep stalling. At high revs no problem. Cylinder compression is fine at 100 all around. If you are facing the motor from the rear I have found water in the top of the cylinder at the top left. The bottom piston on the same side has corrosion on the spark plug which has only been put in two trips ago or about 5 hours running.
The compression being ok confuses me any suggestions as to what could be causing the water to get in.
