I have a Toro Power Max snow blower that I can't get started. I got it last winter and did not use it. It sat in the garage until this past snow fall; I put fresh gas in it and went through the starting procedure and on the first try it acts like it wants to start but doesn't. When you attempt to try again it just cranks but doesn't start. I checked the spark plug gap and it is OK. Could the carbuator be causing the problem?

Did you leave gas in it over the summer? If so, you could have fouled the spark plug or gummed up the carb. I had the same issue with a gas powered chipper/shredder.

If the blower was never started and never had gas, then it could some other gas line issue.
