Ariens 8524 need engine

My Ariens 8524 engine is done, looking for a replacement. The engine in the blower is a Tecumseh HMSK85 it has a main 1" output shaft and then a smaller output shaft.

As far I can tell the Tecumseh HMSK85 is no longer available, anyone know of a replacement? I think the smaller output shaft is for reverse if so can I just remove the belt use an engine with one output shaft and just not have reverse?

Thanks for info!

if your sump cover is still good buy an old hm80 with a solid state ignition(points ones have the cam gear cut different) and clean up your crankshaft and camshaft with muriatic acid. ive done this many of times

If you find a 8hp single shaft the case cover with all the parts will transfer over to the new engine. Just need new gaskets for the case.

Sno-Tek Modded, 15"X-Track tires (Now has same X-Track tires but 13"x4" for better fit), 254cc engine LED light and hand warmers.
Snapper 6/22 sold but not forgotten. Was my first.
Ariens ST1027LE workhorse and going strong.
