Hey Bill,

I had a 205 with a 5 hp B&S engine. Unfortunately, I can't give you any advice on how to do it as mine had the B&S on it before I bought it. I can tell you that there were absolutely no issues with the operation of the 205 with the B&S vs. the Acme engine. Have you called Joel Dufour at Earth Tools in Owenton Kentucky? He could give you all the information you're requesting and much more.

Good luck with the conversion. The 205 was a lower cost machine BCS made to compete with other manufacturers on price, but it's still better than anything else on the market. I only sold mine because I couldn't find a snow blower for it. Of course, now that it's gone, I've found half a dozen I coulda bought :-(

Bill
