Toro Snowthrower Castostraphic Loss of Power

I have had a Toro CCR 2450 snowthrower that has worked great for the past few years. I've used it a few times this year without incident, but today something went wrong. I started it up and it started the first pull. However it reved very high for several seconds and then the running normalized. This reving was very high and I have never heard it run like that. It sounded like it was running okay, even when I engaged the blades, but as soon as I hit the snow, the load of the snow really slowed down the engine. It only threw the snow a few feet at first but then didn't even do that and sounded like the engine was going to quit until I stopped pushing it and it reved up to normal sound again. Every time I pushed it into the snow the engine would slow way down. The snowfall I was trying to clear was about 6 inches deep but this snowthrower has handled even deeper with no problem. Anyone have any ideas? I'm thinking it might be the carberuator. |

Sounds like your throttle shaft is gummed up and not turning freely. If you can work the throttle shaft by hand... With the engine off, twist the throttle shaft from full throttle to idle.... If the shaft only returns slowly it is gummed up... The throttle shaft should return to the spot it is set with a "snap"... If you think it is gummed up, spray some carb cleaner on ont shaft and work it around.... Good Luck Friiy I removed the covers to look at the engine, and the throttle shaft you speak of. Wasn't sure if I was looking at the right thing but right between the carb and engine there was a spring attached to an 's' type of bracket and also linked to something the obviously rotated inside the carb. I moved it back and for but the spring didn't seem to have any effect on it since whatever moved seem to stay in the position I left it in. I moved it back and for several times to loosen it up, it seemed to move a bit more freely but not enough that the spring was a factor. Maybe that is the thing that is gummed up you were talking about.
