We use to have one Brand New in the Box and it was given to our Sachs-Dolmar Distributor of the Year, Husky Power in Shreveport, LA. They have since gone out of business and I never heard what happen to it after the owner of the Company Jim Thompson from Charlotte died. I heard one run one time and it sounded like a little small block V-8. The saw did not have vibration dampers as it just did not vibrate. The muffler was the problem. The rotary engine in the Mazda has two spark plugs/rotor to burn all the fuel. The Sachs version of the engine only had 1 plug (you're getting ahead of me). There was a little extra fuel making it to the muffler and caused the heat temperature to rise. I was told by one guy that he used the 3.5 cubic inch 8hp engine in a go cart and said it kicked assss. However he routed the muffler under his seat and roasted his own assss.
