IIRC, it should be around 150ish per cylinder. Main thing to watch for is a cylinder that's way out of line from the others. So, if you get 150-150-150-150 then you're ok. If you get something like 150-150-35-150 then you've got a problem.

Ok, how to do it. Squirt a little oil (not a whole lot) into the cylinder. Screw in the compression guage. With all the spark plugs removed, and the throttle wide open, crank the engine over for a few seconds or until the guage quits moving up.
