Ok after trying to reset the points over and over again, I found that the contact on point breaker was loose and I could not get the exact gap .020. In the meantime I took apart the head, and rechecked the valve to tappet clearances, went to top dead center and readjusted the clearances. Reasembled the breather plate properly, and got the engine running again real good 3600 RPM the hole nine yards, and then the point gap went again, must have thrown the timing off, it stalled and the engine was so hot you could fry an egg on hood of tractor. Is this normal reason to make engine so hot?? or do I not have the carb set correctly (3 1/4 top screw and 2 1/2 bottom screw?)?? After I reset the valve to tappet clearences conducted multiple leakdown tests, and I got readings from 40% to just outside of green area in the 45% range, so the reseting of the valves made an improvement (was 70% before valves were reset.) I bought a new set of breaker points (kohler product this time, the last one came with rebuild kit...junk). I will try to install the new points tomorrow and report back. Any help would be greatly appreciated as to what is causing the engine to get so hot. I cant even touch the dash tower!

Do you still have to the correct carb on this or did you change it?

Do you have the correct amount of oil in the engine (the amount the manual says vs. waht teh dipstick indicates?

Hot hood doesnt surprise me but I dont know how hot is HOT???????

Is timing supposed to be at 0 degrees?

What fuel are you burning in this?
