      I can see why Al Nunley always said to get a good comp tester. Second time the little pin on the check valve broke off ruining another motor of mine. Don’t buy from the well known tool discounter here in the US. ya get what ya pay for.

      I just use a long 5/16″ allen wrench in the starter nut. You can tell if it has enough compression when you prop it over.
