I have a question on a 10 horse troybilt snow blower. Was using it this morning and the drive wheels stopped. took off the top belt cover first to check for a broken belt. belts are ok. when I squeeze the beater handle the idler wheel moves over, tightens the belt and they work fine. when I squeeze the drive handle the idler pulley does not move. when I took off the bottom cover a spring fell out. looking at the idler pulley I see a smaller spring hooked on the idler pulley bolt but the other end of the spring is broke off. I cant see where either of these two springs are supposed to be hooked up. the wheels are driven by a friction plate coming in contact with a rubber wheel. can anyone out there help?? e mail is [email]jkhoppy@gmail.com[/email] thank you

I recently picked up a Stihl MS290 on Ebay at what I would consider quite a deal. The lady had it listed as "for parts" The reason she listed it that way was because the chain brake handle is broken off and there was a crack in the rear handle. SOB runs like its brand new though. She told me that anyway. Thing looks great and runs great. How much trouble is it to repair that chain brake? She told me they have used it that way for well over a year but for safety's sake, I thought it might be wise. Thanks
