I have a SRM-210 just had a carb rebuild kit to it and it dosen't stay running no matter how much play with the choke.I guess my next step is to buy a carb.Where can I get a new carb without it costing me a arm and a leg.I was toid by a dealer to just buy a new machine,because mine is about 10 years old.My problem is I like this machine and it still looks pretty new and was running great.Can you help me or am I stuck buying a Stil?
