long story short
replaced tstat and head gasket
glass sanded both sides of the head and water jacket
cleaned all crud off head and piston.
ran the motor for about ten minutes to check cooling and leaks.
checked compression:
hand pull, 6 strokes 115/115
use a drill, 130/140.
why the big difference between pulling and using a drill at low speed (poor mans starter), should i have concerns that i have a 10 psi difference between the two? i know about the 10 % rule, or 13 psi diff. i just am a little curious if i need to have any concerns?
before i replaced the head gasket the compression was 100/100.
thanks
