Also, why is my Craftsman snowblower surging?
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.
Beside above, is it OK to run snowblower with choke on? When the passages start to plug up the engine does not get the needed fuel to run smoothly. Then when you choke the engine, it delivers more fuel and the engine will smooth out. Please use extreme caution when dealing with fuel. Then after you have cleaned the carburetor, start the engine and slowly turn the choke off.
One may also ask, why does my Ariens snowblower surge?
If it's surging or hunting try to give it a little choke and see if it settles down. If so it's running lean and might be something is loose and allowing an air leak or there is a problem with the carburetor.
What does it mean when your snowblower backfires?
If your snowblower is backfiring, the problem can be traced back to one of three reasons. The first one is running too lean. The second issue could be incorrect timing (this could be about the valve or the spark); and the third issue that could be causing the backfire is the inlet valve not seating correctly.
