Hey guys, thanks for letting me join your group. I have a To20 that I recently restored mechanically. I sent block and head out to be baked and cleaned. And bought all brand new everything except crank. Which was in perfect shape. I had the motor professionally assembled. Then put it back on tractor with brand new radiator, hoses and rebuilt water pump. It runs great after a few hours of figuring out the timing. My problem is everytime I turn the throttle back to an idle it dumps alot of antifreeze out overflow. If I loosen cap, it will dump out cap too on deceleration. I know it's only supposed to be about 3/4 full or so but, it won't stop doing it. I just added about a gal. or more. Any thoughts? Remember everything is new.
