Generally speaking, without the exact factory spec., you should have over 60lbs., but you may find your motor will run with less. Even if the number comes out low, spray some WD40 into both cylinders throught spark plug holes. turn engine over couple dozen times. Spray a little more WD40 into cylinders and replace one plug, putting compression tester into other spark plug hole. Retest..If numbers improve it is bacause you have some rust that has formed on cylinder walls and it will take a bit of working piston to get it seated back in properly. P.S. My old 3hp Lightwin has 70lbs. in both cylinders.
