So, my local Stihl dealers are much more willing to negotiate a price (local Husky dealer just quotes me only MSRP!). So, I'm thinking about getting an MS661CM power head only when they come off recall. I've already got a 32", 0.050". 3/8" bar and chains. I could always get some longer bars/chains as needed. Anyone got a66ny feedback? Anyone got an M-tronic Stihl vs. manual adjust carb? I'd really like to know. MS660's should be flying off the shelves for the next couple of months. Would I be better with the adjustability of the MS660?
