I can't remember for sure but I think it was 120 or a little higher , not sure if I did it right just held it in and cranked over the motor
Expert:  Steve replied 3 months ago.

low compression could be a cause of your problem and is something that would come on gradually and gradually get worse. we might as well get it out of he way now.

perform a compression test.

- remove both spark plugs.

- install the compression tester inn the front cylinder spark plug hole.

- hold the throttle wide open and crank the starter while observing the gauge.

note what the gauge reads on the first, second, third, fourth and fifth stroke. the first 4 don't need to be exact, but close as you can.

- repeat with the rear cylinder.

let me know what you find.
