    It's a good choice for a powerplant, Tanker. There's good and bad points, but I think in this case the good outweighs the bad. They have chrome cylinder liners, so they wear like, well, chrome, but when they finally do wear out the recomended fix is jug replacement. They're a five-port engine and you'll get really good performance for the size and weight. They were really popular in snowmobiles and ATVs, so parts are still pretty easy to come by when you need them.

    Im not exactly sure but Id imagine that it is somewhere between 35-40 HP. Don, I was reading on my Wiesco Piston box that it said not to install these pistons and rings in chrome plated cylinders. I never thought that there were many engines that had them, but now I know.........you learn something new every day!

    The single carb model was 37 HP and I think the twin carb was rated 44.

    37 horsepower, that should move the wedge right along with the proper gearing.


    about a 20:1 gas/oil mix?
