Re: Compression test results?
take the hose off of the compression guage, and hook it to your shop air at about 40 psi to start.
CHOCK THE TIRES, PUT IT IN NUETRAL
bring each cylinder to firing position, ( both valves closed) and screw the guage into that plug hole and pressurize, then listen for the leak, increase pressure if you need to, Id do this on each cylinder, you might have a bad head gasket or head sealing problem between 3 and 4.
youll hear the air hiss thru the exhaust, or carb, or bubble in teh radiator.
