I guess next time I better go to the source before saying anything. I do think it's rather sad that the LHS owner would lie to me about such a matter. I guess he's just trying to get rid of the engines he can't sell. As the Senoir Instructor of our club the MDS is the only engine I will not recommend to any one. IMO it is the worst engine on the market, the GMS & Tower line run a close 2nd and 3rd. the carb problem they talk about did not solve the bad and erratic settings on the engines
