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.
