Lost my temper today.
A few years back I bought a used snowblower from a seller online. It was a fairly new machine, his reason for selling it was that he had bought a small tractor and no longer needed it. I picked it up and brought it home, was early fall, still a few weeks before the first snowfall. I gave it a good once over, changed the oil and sparkplug and it ran good. Fast forward about 5 weeks and the first good dump of the white crap hits, the damned thing won't start. I yanked on the rope until I thought I'd pulled my shoulder out, no way it would start. I checked for spark, and I had filled it with fresh gas before I tried starting it, but no way it would start. I dragged it into my garage and plugged in the electric starter, still no start. Cranked it until the starter cut out. By now I have been at it for over an hour, in 10 degree weather, and my wife has started to shovel the snow. I grabbed a can of carb cleaner and sprayed it into the carb throat, finally the stupid thing sputtered to life. After spending another hour and a half cleaning the snow with the machine, I shut it down. It would restart with no problems every time I tried it that night. The next time I used it, same thing happened. I finally took it apart and found that the primer hose had been chewed up by mice, likely before I bought it as the first owner lived in a rural area.
