Seat-inlet 801317

Had 2 Toro snow blowers in the shop the same month with B&S engines, plastic carbs and same issue. A good thorough cleaning, new seat/needle and bowl gasket did the trick. Make sure ALL the small fuel/air holes are cleaned including main jet. Plenty of great You Tube videos on that. Potential problem if carb is over tightened when re-installing could lead to throttle shaft binding. Move the throttle shaft & governor spring to make sure it doesn't bind every-so-often when tightening carb. If possible check for proper RPM before replacing bottom shroud. Specs vary a bit depending on your model.

Most important, always use fresh gas/oil mix; drain & run dry for summer storage. Start the new season with fresh gas/oil mix too. Difficulty of repair will vary. Take it slow.
