Backfire cure?

Recommended Posts

I alow mine to idle for 5 minutes, I know some may deem this as long, but I really think it is for the better, it allows the motor to cool itself down and it doesn't backfire, I have never had this happen on my old lawnmowers (Afterfire) except for my new Regent, even with the solenoid, it will backfire so I allow it to idle and it will not do that,good luck,-BradW

Been reading through previous posts regarding backfire problems. Usually occurring when shutting off after running your tractor for a long time at high speed. I have had this same problem on both Briggs and Kohler engines. The traditional "let it idle for 30 seconds before shutting off" helps some but still backfires frequently. I have discovered if I pull the choke lever to full choke when shutting off the tractors, in combination with the 30 sec. idle, I never, ever, get a backfire or "afterfire". I have done this numerous times over the past year and it worked every time. I get a backfire every time I do not do it. Anyone know of any negatives about this practice??? Hearing my neighbor's backfiring "Huskie" yesterday reminded me to ask about this. Brent

Hi Brent, I don't know about that one. Its sending alot of raw gas into the hot cylinder and basically choking the engine out. Also its seems like it would be sending more raw gas into the hot muffler. What happens to cause this popping thru the muffler is raw gas being sent into the muffler and the muffler being so hot it actually ecnites the gas inside the muffler. It just seems that you might end of fouling a spark spug after awhile. I can't really say for sure other then I turned the idle down a knoch more and then I only have to wait about 10 seconds for the engine to idle down and now no more POPing. Hopefully someone else can address this better then me. Take care, >>->happyjack<-<<

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
