Oh, I know the Predator is junk. I'm not denying that. It was $129 NEW!!
I'm smart enough to run, operate, repair, and maintain anything. I bought this Tractor JUST AS YOU SEE IT. I didn't put that motor in it.
But I've had trouble with the 2 Tecumseh's I've owned. Both were abused and I inherited the problems. Parts can be tough to find and condition of parts is always questionable. Price of used parts can be all over the place as well.
I got that tractor for $200. That's CHEAP. And it runs GREAT!! I have no interest in spending $400-600 for a nice Tecumseh that it originally came with.... Why?? This might be the coolest, most fun, and functional thing I've ever purchased for that kind of money.
