1940 Farmall A

Tractor runs real good but it is a little hard starting when you first start it. We did a compression test it had 90 or slightly above on all cylinders. We did a wet test next and it went up just a couple of points,it didn't change much. What do you think is this too low or should it be higher? The tractor does not seem to burn oil. Thanks for any help. Randy

I would consider 90 on all cylinders as good. Seafoam may bring it up some more.
I'm assuming that you are using a starter not a handcrank. An old starter with dirt and worn brushes inside will crank hard. A fresh rebuild on my cubs starter went from hard starting to an amazing start. As far as hand cranking, for my "A", when its cold that thing is really, really hard to handcrank. Its much easier when its warm. I let the starter do the work when its cold.
Kickback hurts!
