What to do with my backfiring Briggs Engine on My New Ariens Snowblower
Original Message   Dec 26, 2009 11:24 am
I purchased a brand new Ariens Platinum deluxe 24" snowblower in October of 2009.  I paid $2000 Canadian with tax.  A few weeks ago, I used the machine for the first time to clear about 5 cm of snow.  Unit started up well and removed the snow.  Then, when I went to shut down the unit, it backfired and two flames/sparks came out of the exhuast.  I went to start the machine up again and it wouldn't start even though it had been running for 20 minutes.  So, I opened up the choke, primed the unit and it started.  Upon shutting down, the backfiring happened again and again it wouldn't start.  So, I contacted Ariens.  There response was:
1. Put the throttle down to half, let it idle for about 30 seconds and then shut it down.
I did that and still the backfiring happened.  So back I go to contact Ariens.  They tell me to take it back to the dealer.  I did and they:
1. changed the camshaft
2. started 4 other Ariens machines and they all did the same thing.
3. Contacted Briggs who told them the backfiring is caused by the engine running lean so that they could make it through emission restrictions.  They also told the dealer to tell me not to worry about it.

At this stage, I'm frustrated.  I find it unacceptable to pay $2000 for a machine and have it backfire right from the get go.   Interestingly enough, the dealer had a single stage toro 421 and a powerlite.  Both units come with the 4 stroke Chinese made engine from Loncin.  He started those up and neither one of them backfired.  

I don't understand how Briggs can let this go.

Now, I don't know whether to:
1. Just keep the unit.
2. Push Ariens to do something about the unit.  Ariens uses the snow series Briggs.  I wonder if the Snow Max series does the same thing.
3. Push Ariens to give me my money back.

Any idea/feedback?

Wow... well, hopefully the new models have fixed some of those bugs.  Haven't experienced slippage yet, but will know it when I see it.  Hard to believe that such a specialized company as Ariens could blow it big-time on key design execution.

The Ariens at work was purchased new 2 seasons ago.  The first year for the Briggs and trigger control.   The engine just does not fit right on the machine.  Very hard to work the throttle and gas valve. 

The trigger control works and does not work.  The drive slips when the unit gets wet and then the machine sits and there is no way to move it unless you push.  Ariens came out with a mod for this but does not help.

   The balance of the machine is off.  Way back heavy.  The tires are way too small for the machine. 

  The rust in 2 seasons is horrible.   The engine runs strong and smooth but thats about all that does.

  Maybe they have made some better changes in the last 2 seasons. 

 My 1128DLE is from 2003/2004 purchased new and love it. 

  Have a 94 824 purchased new and love it.  Have had many older units and had great luck with them as well.


Good observations.

I'm finding the same issues with my new Ariens, especially:
1. The drive does slip when the unit gets wet.
2. The machine is back heavy, making it tough to turn.  Equivalent Toros of the same weight are much easier to turn.  One thing I've noticed is that the Ariens units are shorter than Toros.  So, I think is more evenly distributed on the toros than on the ariens.

My brother-in-law bought his Ariens in 1999.  10 years later, he's had no problems.  Something seems to have happened to Ariens quality control since they went into Home Depot in 2002 or 2003.

I heard from my dealer new engines have emission requirements that cause them to run a little different than in past. My platinum deluxe 24 did the same thing when idling down. Make sure your choke is all the way off also.

I don't understand all the fuss on this one.  Is it affecting performace or damaging the equipment?  If so, it should be fixed.  Otherwise, turn it off and go inside for some hot coffee.  My Dad has a 15 year-old Ariens (obviously, Tecumseh L head).  He never does anything except change the oil and lube the auger shaft -- that's it.  Since day one, it has been nearly impossible to turn off the machine without a backfire.  You have to creep the throttle down ever so slowly and then MAYBE it won't backfire when you cut the spark.  I have a four year-old Simp Pro with B&S OHV.  It's backfired on me just twice.  However, because of my experience with the Tecumseh, I always carefully throttle down to stop the machine.  And I never cut the spark.  The two times: Once, I was starting to get ready for the season.  Machine started up, but I didn't get the choke off fast enough.  It sputtered, stopped, and backfired.  The other time was when I took the throttle down too fast, the machine stopped and backfired -- just like my Dad's.

I've seen Briggs engines in other applications back fire just about every time they're shut off. I have a friend with a Toro lawn tractor that has a 16 h.p. single B&S engine. Big bang pretty much every time he shuts it down, no matter what method he uses. Personally, I think it might be residual fuel in the hot exhaust igniting as soon as it has enough oxygen mixed with it. The "EPA/lean carb setting" is a little mysterious to me. One would think that setting the carb extra lean would deprive the opportunity for fuel to accumulate and ignite. If the back firing is due to fuel in the exhaust, all it would take is a glowing metal shard or burr inside the exhaust to ignite it. It's not uncommon for parts of an exhaust system to glow cherry red after only a few minutes of use.

If I where in your position  I would, contact Ariens  and get your money back!!!!!!!! You paid $2000.00 .

Don't let another day go bye, Do you want to deal with this problem every time you use it . Time is running out. Don't live with buyers remorse you paid $2000.00

Add me to the list.

Bought the same model as the OP, US version and it's now two years old.  Finally had some snow so first time used.

It backfired shutting down and even changing speeds from, what's it called now.... rabbit speed to tortoise speed idle.

Will this damage the engine, or just scare the heck out of whoever's using it?

What happens on these extra lean running engines is that the muffler gets very hot as a result of the lean burn condition of the engine.  If you turn off the engine at full throttle when the engine is hot all that is happening is that the spark is killed to the spark plug but fuel is still being dumped into the engine because the throttle is wide open.  The unburnt full is then pumped out of the cylinder into the burning hot muffler.  When enough air is mixed with the unburnt fuel BOOM.  This will not harm the engine in any way but running that lean might.  If you have a throttle idle the engine down slowly and let it sit for a minute or two at idle for the muffler to cool down some before turning it off.

Like the other said, the lean carb jetting, and it could be the ignition timing setting. Your dealer is never going to help you because the factory will void the warranty if the dealer changes what needs changing (carb tuning and maybe the timing) pus the legal issues.

The muffler could also have a catalytic converter inside- take off the muffler and look for a honeycomb plate or chamber inside. You can decide haw to handle that.

I stopped buying the newer OPE and only buy and fix older units. EPA is sheeiit.
