1990 Force 150 cylinder problems

[sledstew]

I just bought a force 150 and the top cylinder read 80 lbs compression, when I do a leakdown test on the cylinder is shows that its perfect,I was wondering if anyone has ran across a similar problem.I was thinking of using seafoam to DECARBON THE RINGS HOPING THAT WOULD BRING UP THE COMPRESSION.aNY HELP IS APPRECIATED IN ADVANCE.tHIS MOTOR LOOKS LIKE NEW AND THE OTHER CYLINDERS ARE AT 140-145 LBS COMPRESSION.

have you pulled the head and checked for damage to the gasket? also look down the problem cylinder walls and see what it looks like

yes I pulled the head and the gasket looks great and the cylinder walls look good also.
