buddy of mine is having problems with this motor.cleaned carbs new fuel tried 2 different tanks took coils off running motor no different compression 98 96 92 new plugs could this need a head gasket this compression seems low with my guage
I would usually agree with boobie but not this time. Your compression is bad enough to look at that first. Yes a head gasket can fail.but usually not on all 3. Time to pull the head.
Do.you have all the plugs out when you are doing a compression test. could be anything a bad gauge, bad head gasket or motor not turning fast enough. Or the motor is worn out I am not there. A head gasket costs around $20 cheap enough for a look see.
No you pull all the plugs out for a compression test. You need it to spin as fast as possible. Pull the safety lanyard off to kill spark and run another test with all the plugs out.
my buddy took the head off today.He said cylinders looked good,no scoring.He said head gasket did not look blower around the cylinders.There were some disruptions around the water jackets but I don't see where this would effect anything.I am not sure he or I know what to look for.The only scored cylinders I have seen were on a chainsaw and it was obvious.
