Default Re: Why is there no compression unless

Motor spinning backwards?
Set the valve air gap first.
Follow the valves for proper rotation.
Piston rotates down as intake opens then closes, piston rotates up to compression, ignition and down on power stroke, piston rotates back up as exhaust opens and closes, starts over.
