I have a Toro snowblower that I have had good luck with, 'till this year when it snowed.
It's powered by 5hp Tecumseh engine. In late fall I test ran it for a few minutes to make sure all was well. Started and ran well. Now that it's cold and snowing in Minnesota, when I need it, I'm having trouble. It's very hard to start, and when it does start it will run for 2 or 3 seconds then die. After it dies, it will not start at all. I tried fresh gas, and that didn't work. I put some Seafoam in the tank and let it sit overnight. Still no go. I have tried many combinations of choke, no choke, prime, no prime, but no results. It seems if I leave it alone for a couple hours, it will start, but then immediately dies.
Any ideas? Thank you.
