Have a Briggs 11.50 that backfires no matter how much I turn throttle down when shutting off. Sometimes see flames shooting out muffler. Dealer says not much adjustment on carb due to new epa regulations. Anyone have same problem. Mine is a 24" ariens platinum.
I had a similar problem with my Honda. My primary jet was partially plugged (this can happen even on the new one) and the dealer cleaned the primary jet in an ultrasonic bath. No more back firing after the clean. Ask the dealer to perform a primary jet cleanning job if you have warranty. Good luck. It is not going to snow this year. I may have to cut the grass again - I love this global warming thing!
