Why does my snowblower surge at high speed?
Idle is smooth. With the throttle in the fast position (full throttle) the engine surges, unless there is alot of snow going into it, then it will smooth out at high speed, but as soon as the load is off, it will start surging soon or immediately. Returning the throttle to low idle will smooth out the surge.
