RE: Lightest Engine
I am still going to get one. I want to see what my engine does on it. I don't think it will match the G26, but should be close. We will see. If it helped the Homelite as you said, the Toro's I build should out do that little tank by far. I know on an APC 16x8 there is a large gap between my Toro and the Homey 25.
Oh, If you want EI from TommyRC you will need to contact Adam at BCMA engines. He is going to be a dealer on it. That may be why he is not answering you. I think the cost will be higher than $40 though. I am sure the $40 price didn't include shipping from China.
