"Hi,

"Hi,
I have a strong spark out of the spark wire to the motor chassis. The motor dies only when in the water and under the load. Looks like the combustion pressure "weakens" the spark.
After examining the spark plugs I found that there are tiny black holes in the ceramic insulator all around within the same circumference.
Is the spark escaping from there to the chassis when under pressure?"
