My new best friend
I have an old Toro 421 that was made in 1981. The thing is just plain awesome. I might actually buy a new spark plug for it this year...it still has the original. They don't make 'em as heavy duty anymore...mine has a steel chute and the same drive gear and belt sizes as todays 10hp models with 4hp.
Plus the Tecumseh 4hp engine will run on stale gas just fine too!
Typically if a snow blower doesn't start, it has water in the fuel bowl...pull it off, dump it out, and i bet it will start.
