Does this rule out the head gasket. Could not get it started yesterday without cranking for along time.

You need a couple of good decarbonizations!

Cann't do the carb. switch thing.<br />Need to check the compression warm for a accurate acessment. Sounds like your cold #'s are in the ball park so head gasket is probably not blown.<br />Noticed you've posted alot on this particular motor, think its time to unload your Force and get a solid motor that you don't have to constantly be messing with? <br />I did, my 1996 Force 75 is long gone and I'm very pleased with my new Mercury. Just call me "dclean" now Just a thought...
