my 1985 50hp lost compression on bottom cyl, has set up for over a year, craked it up and ran fine for around 10 minutes, then started missing, checked carbs, fire, all ok, check comp today, top cy 130 lbs, bottom cyl 75 lbs, would it maybe be the cyl head gasket or worse, head or cylinder rings, hoping not too bad
