running problem with sears craftsman 7.75 HP snowthrower?

I had a similar problem which I think I cleared up by using a gas stabilizer every other tank of gas. It took out the moisture and freed up the gummy residue from sitting. I tried a new spark plug and did all the usual maintenance and the gas stabilizer seemed to help me. Over all this Blower 88775 is a great machine. Sears told me that it was not electrical so I tried everything pertaining to the fuel and carberator.
Good Luck and I hope this helps you.

That sounds like a failing ignition coil, but first check to see that the fuel fill cap vent holes are clear. If their plugged up you'll get the same symptoms.
