Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I just purchased a new Husqvarna 9hp snowblower in November 2008.  From the first time I used it it seem to have a miss when it not under a load.  When I am finished using the snowblower and I slide the throttle to off the engine backfires.  I thought that maybe I was turning it off too quickly, but when I slide it off slowley it still backfires.  I brought it back to the dealer I was told that is the way they run due to EPA standards, and there is no carburator to adjust.  Is this true? or am I being brushed off by the dealer.  Should I take it back to the dealer and insist it be corrected or will I have to live with a backfiring, missing engine forever.  Any help would be appreciated.  Thanks.

Do you know of a phone number for a technician at Tecumseh that I can call?  I would like to take some information back to the shop where I bought the blower to let them know that something can be done to my 9hp Tecumseh on this Husqvarna snowblower.  Something to ease the missing and backfiring.  Thanks.
