How much do you know about gasoline engines?

does it get run for more than an hour at a time?

Does the tractor run well, or misfire on one or more cyl.

Have you pulled the plugs to "read them"

Things I would do. (after assuring oil in the engine is up to full, coolant is up to about 1.5 inches from the neck of radiator)

1] run it for an hour doing something important and working the engine. Observe the amount of smoke, and take notes.

2] If it smokes hard, I would pull the plugs and keep them in order then describe each in your notes as to color and substances on the working tip.

3] I would take a compression check on each cylinder (throttle open ignition off) write it in the notes.

4] get back to us for further analysis. all remaining ideas need this first info.

it runs blue for several seconds and then clears up. I figured it was valve guides, but my uncle rebuilt the motor 3 years ago and it had been sitting idle since then. All spark plugs look good after trying to get it to stay running. No fouling or slick plugs.
