Mix 1 quart of ATF in 3 gal of gas and run it on that mix. ATF cleans up carbon etc. in an engine. You could also add ATF to each cylinder and let it sit a day or 2 that way then pull the plugs and spin it over to clear out the ATF and then run it.

i will try that, do you put straight atf oil into the cylinders no mixing?

What does "it's slow" mean? What weight oil is in tractor? Stuck valves are going to cause more symptoms that "it's slow"
