Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a Techumseh HMSK80 and am thinking of replacing it with a Subaru SK30 engine. Has anyone used this engine on a snowblower before? It puts out 9.5 hp and revs to 4000 . Is it a quality engine. I was thinking of something different , and better performance than a Techumseh HMSK80. I cant find a NEW  10 ,11 or13 hp Techumseh HMSK engine.I here Honda clones have to many problems. I was told Briggs & Stratton Vibrate more than Techumseh. A REAL Honda GX340 is outstanding but cost is very high. That leads me back to subaru. I want to here from folks that  are using them. I want to repower my  serial #924108 Ariens Snowblower

I doubt you can get the Subaru as an after-market engine (only Ariens uses them) and they certainly will be expensive. It is a commercial engine built with full automation in Japan (even the GX is made in Taiwan).

Borat had the right idea. Small Engine Warehouse has several engines that will work for you. There is only one with the truly correct crankshaft extension (Tecumseh #3, 1" diameter).  It's a Tecumseh 11hp OHV Snow King. I myself would get the HMSK100 (re:358cc L-head) with the adaptor for the 3/4" crankshaft (displacement is your friend). The output on these is rather beastly.
