Mark I am needing to check my compression in my 37A too. I was going to make a adaptor out of a old plug.My tractor is running on one cylinder and has lots of blow by.When it warms up some im going to check mine.How would be the best way to check a hand start?Im thinking getting someone to pull it like if you was to pull start it and then i could walk beside it and read the gauge.I dont know if hand cranking it would be fast enough to get a good reading.

Hook TWO together using a flat belt on the belt pulleys. Best way to turn them for tests.

You're right that hand cranking would be too slow. Pulling it will be ok but you need to determine the correct speed for the test. Too fast will show higher compression.

Hand cranking it works fine. Make sure the throttle is wide open. Run it through about 3 cycles with a tester that holds the pressure. They need very little compression to run nice if your carb is set right & ignition is strong. To strengthen #2 try richen the idle mixture. Turn the idle mixture needle counter clockwise a full turn or more & see if it gets stronger or just smokes. I suspect weak ignition if that dont help. A sticking valve is also possible
