I just took my 2011 cub cadet snowblower out of storage. I put sea foam in it before I put it away. It would not start after several attempts so added gas (gas was about 5 months old) to delute the sea foam. After several more attempts now with the electric start I had no success in it even attempting to start. I let it sit for about 30 minutes and tried again and it started. I let it idle on choke for about 5-10 min and it would not idle if I took off the full choke. I let it idle a bit longer and had to operate with full choke for my entire driveway. (It seemed to Have less power). I completed the driveway and then tried again to back off the lchoke but it stalled everytime so I it idle another 10 minutes still having it stall after backing off the choke. It was brand new last season with a very mild winter so this is really disappointing.
