Hi Abe, Is the compression on all cylinders within a few pounds of each other? Has the tractor been running ok and all of a sudden the
compression is very low?

Remove No.1 plug and have someone rotate engine until you feel compression against
your thumb. When you feel compression, stop the
rotation and look for the timimg marks. You should be close to your pointer. Slowly rotate engine until the timing marks are aligned.

Remove distributor cap and see if rotor
points to No1 position on the distributor. If it
doesn't, the valve timing may slipped for some reason. In this position both valves on No1 cylinder should be closed, you could check your
valve clearance with a feeler gauge.

If the timing appears ok, squirt some
engine oil into each cylinder and then recheck the
compression. If the compression is alot higher,
you probably need to overhaul the engine. Good Luck, Hal
