Troybilt snowblower starts runs good for 20seconds as soon as you are in heavier snow runs rough and backfires and sputter, just put on a new carburator, still doing the same

Hi Janice,
Sorry to hear you are having problems. If this is a 2-stage snowblower, they typically have a carb box that covers them. I would try running it without this, not as a permanent fix, but just to see if the blower performs better in the heavier snow. If it does, than it may be that the carb is in need of more air and might need an adjustment. If this is a single stage snowblower, then the carb still may need an adjustment. Not all carbs are adjustable and I know you said you just got a new one, but depending on how old a unit this is, it could be the problem. If you want to provide model/serial number of the engine, i can try to find it and see what kind of carb it is using.

Snow blower runs well then dies to a rough idle

Sounds like it has dirt or water in the carb and is slowing down the fuel flow and starving the engine of fuel.

Running rough and backfire

Sounds like a timing problem(flywheel key) sometimes the key will shear part way do to wear, flywheel key is located on crank end under flywheel, disassemble air housing to expose flywheel crank nut unscrew nut (impact) to see key and keyway slot in crank determine that key is not sheard and is in center of crank keyway slot. if sheared you will have to use a puller to remove flywheel from crank. install new key and reinstall flywheel with an impact gun .
