Well after rebuilding starter,and replacing both solenoids I have the ole beast turning over. In the mean time I had been changing fluids and such. So tonight I bought a brand new compression guage from sears.I removed all 4 plugs and just cranked it a bit. I wanted to fill the new oil filter. So I then hooked the guage up. Keep in mind its a 4cyl. Both exteriorpistons pumped out 170psi and the middle two 140-150psi. I squirted some 80w oil into the middle cylinders and didn't do much maybe 5 or 10 psi more. So i'm figuring leaky head gasket between those two? I also squirted some oil into the exterior cylinders and got 10 psi more out of those. The manual says 150 psi is normal...so it has me thinking. I think next I'm gonna get some fuel into it and get it running,warm it up and see what kind of results I get. This motor has sat 8 years or better, and tonight is the first action its seen that I know of. I'd like to hear a few opinions on my compression results. Ultamitly I have 20 psi difference amoung the 4 cylinders. Also I have the motor on a stand in my garage, I plan on rigging the garden hose to the raw water hose that comes from the lower unit. Water is gonna be shooting out the exhaust pipe!! Also what about back pressure on the exhaust, all I have on it is the riser/water resevior. Do I need to do anything to the exhaust besides point it out my garage door?!!LOL
