Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Really these units are similar, but if you ask a dealer you'd think they were exact opposites.  Never used a lever traction system like the Toro, but did briefly try the auto trac on the Ariens.  I live 1/2 hr from Brillion WI and really do feel an attraction to Ariens, but that is another issue... Help me out guys!  I'll be pissed if I choose wrong.  Price is the same.

Ariens has offered to send me a new chute pedestal (support rod) and some Ariens orange touch-up paint for the chips, but told me I would have to talk to Briggs about the backfiring engine.  It seems this is a common enough event that Briggs has adddressed it in one of their FAQs.  They say that it will NOT hurt the engine.  There is supposedly no adjustment screw for the carb...just a fixed jet.  The throttle should run at full speed during normal operation.  Any throttling down must be done verrrry slowly in order to avoid the backfiring issue.  They don't say why it is that way though.  The engine runs fine at speed...just don't shut off the key from full throttle & reduce throttle really slowly.  Have any of you Toro owners experienced this backfiring issue with your Briggs snow series motors?

My Toro 1028 does not backfire when I OFF the throttle. I just push the lever all teh way left and it rumbles dead quickly. One pull to start it up again. I have a Briggs engine not sure of the exact size because it's being serviced right now. But mine for certain does not backfire. It sounds like you got a lemon.

Slinger,

So how did you make out with the Ariens? I just purchased a Deluxe 28 with the 250cc briggs motor and it does the same damn thing! I very much do not car for the backfiring. I don't think it is good for the engine or my ears. Have you pursued Briggs or HD any farther to see whether you should get a new motor or did you return your machine?
I am really considering returning the machine and probably getting the deluxe 30, the platinum 28, or possible a john deere. (i'm dealing at my local john deere)
Looking forward to hearing from you.
thanks

I think that your dealer is to blame for that one, not the Ariens factory. I had to put that piece on in the assembly of my boxed Deluxe 28.

NotMoneyGuy,

Your signature says you own a Dulex 28, does your machine backfire when you idle down from operating speed?

It has done it once or twice. I will try to slowly turn down the speed as mentioned above.

Edit: Here is a B&S FAQ link.

Slinger-

Backfiring is caused by the winter fuel and the overlean fixed jet that the govt. requires in today's standards. In the motorcycle community when Harley was using the fixed jet Kehin carbs on the Evo Block ead engines in the early 80's it was standard practice to use a carburetor jetting ream in order to richen the mixture and the backfire and blueing of the exhaust pipes diminished. Harley eventually went to computer controlled fuel injection which is not an option for us.

On blowers as the engine breaks in the problem will diminish a little  but it is something we have to learn to live with.You certainly haven't gotten a "lemon" and will enjoy good service from your machine.

Just a point of interest- When the ope engine manufacturers were first forced to go to fixed jets by the govt. many of us who bought Tecumseh powered units spent the $80 for the old style adjustable jet carb which were still available for the snow engines and the lean run issues went away. Since Briggs had been out of the snow market for about 30 years the new design they introduced for blowers had a new carb with no old ajustable variant available that would fit. The result  is if you got a Briggs you just have to deal with those issues. Interestingly some Briggs owners will report none of these issues with their fixed jet units. This can be explained by the gas available where they live and the altitude at which the engine performs . Honda's don't experience this problem because they manufacture their carbs with several sized fixed jets available.They usually match the engines to the area in which they are sold. I have a pressure washer with a GX Honda that I boought off the net(not from a local dealer).It back fired like crazy until I got my hands on a high altitude jet (rich mixture)and then the problem went away.

Strange.

I've never had an engine that regularly back fired.  I've got several OPE engines within five years old and none of them have that problem.

I am just going to let the engine break in a while and see if the backfiring problem diminishes.  For now I just have to try to remember to throttle down very slowly.  The engine seems to run fine at speed so I'm going to just go with it for now..  I guess as long as it's not  hurting anything (as long as I avoid the conditions that cause the backfiring), I can live with it and see if things improve.
