[eula30]

Hi, I Have an 1977 200hp Johnson, I check the coils today and sparks is coming out right thru the top of one coil and the other one the spark is coming right thru the rubber boot My question is, Motor is not running at Full Throttle, would this be the reason?( A Crack Coil) I check for fuel and fuel is ok, check for compression and this is what I have: 1-128, 2-130,3-128,4-133,5-135,6-130, I think compression seems ok., any help I will really appreciated....<br />Thank you

Wow, arcing coils would certainly do it! Your compression sounds fine.
