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
