ok, i finally got the 41' dug out of the woods last monday, so now its time to think about an engine. the old one is a P-18 motor, its supposed to have a 25" block. that engine is fried as far as im concerned, it sat full of water the last 40+ years and when i pulled the oil drain i got water. its a mess. later, i found a massey harris super 26 combine at the neighbor's farm and earned that by fixing a few tractors for him. the question is, how the h*ll do i get the stupid thing out of the combine without cutting it all apart? its the old type where its at the bottom behind the wheel, and theres no room to work under there. ALSO: does anybody have a decent or rebuildable engine to part with for at most around $100 either?
