Snow Blower surges when Not under load

11 posts in this topic

I have a 2007 Airens snow blower, bought and used it last year. At the end of last winter I added Sta-bil to the gas before I used it the last time. Now this winter I fired her up, and when operating under load it runs great, but when I dis-engage the blower it starts surging and backfiring. As soon as I engage the blower and hit some snow it settles down and runs good. I was thinking maybe it was bad gas, but I ran out the tank and added fresh premium gas, and it's still doing the same thing. It doesn't die, but surges and backfires when not under load. Any ideas appreciated!

If you purchased it from a place that also services them I would just call them.

If it ran fine last year and nobody messed with the carb settings I don't see how a carb adjustment is necessary.

The place I bought it from is now closed (as in bankrupt), but I called the guy I bought it from who works somewhere else now, and he said he had another guy with the same thing, and he thinks the carb needs to be cleaned. Seems to be a fuel issue, the carbs on Airens according to him are non-adjustable, so I'll have to try and pull the carb and see what can be cleaned.

I'd try new spark plug too. Some of those small engines kind of glaze the cylinder with improper spark. Had a chainsaw do that once. Never hurts to clean the carbs though. Also when you put the sta-bil in the gas did you run the machine so it got into the carb too? Did you fog the cylinders? That some times needs some time to burn that oil out and run clean again. Just some thoughts...

Just finished mine,the carb had no adjustment either!(I dont like those) but the governor adjustment did stop the surge.That should have not been the problem so I disassembled and did a complete carb cleaning. Running fine now.

I did all the summerizing required to mine and fired it last end of Oct.Ran fine then! Like I said I dont like the nonadjustable carbs!! Mines a new Troybuilt

Lots of blowers do this I have a Ariens 05 13hp it does it my dad has an older John Deere it does it. It is the govenor adj not a big deal if you adj it too much it will quit surging and just kill the engine. I just leave mine alone.

Ya mean you keep using it while it's surging?? That'd drive me crazy! I like my motors to run the way their designed to.

    • I've been getting them at Costco,  I've checked slyvee and sams but never see them.  Although one of the butcher's at slyvee says he can get them which might not be a bad idea since you can have some fat cut off before you pay per #. I picked one up a couple of weeks ago and it was about 2.80 a #, which isn't too bad yet considering bacon in the store can run quite a bit more than that.  You making bacon or doing pork belly burnt ends moon lake?
    • Excellent summer fishing.  Charters catching strong numbers.  Jig/minnow or jig/leech and bouncers with spinners with crawlers or minnows still producing walleyes. When the wind is right for pulling spinners, they have been lights out.  Walleyes being caught in varying depths, 7-31' of water.  Some shallow shorelines still producing. Pike mixed in all over the lake.    Walleyes in the Rainy River with a better morning/evening bite.  Trolling cranks or pulling spinners a good idea to cover more water. Smallmouth bass are out and about along shorelines and feeder streams. Sturgeon fishing opens again Saturday, July 1st.     Up at the NW Angle, water temps are in the low to mid 60’s. Wind blown shorelines are giving up walleyes via leeches or crankbaits along the weed line. Crawlers on a  gold and/or orange spinner are producing fish out of the mud between 22 - 26 feet. On the Canadian side, bottom bouncers and spinners have been filling the livewells outside of monument bay between 24-28 feet.  Jigging near Skeet and Kennedy Islands have produced nice sized walleye and numerous perch. Great smallmouth action in Tranquil channel and the mouth of Johnston passage. Muskie fishing picking up with high 40” class fish being caught with a few 50's from shallow bottom bays or adjacent to them.
    • Busy time of year out there so if u get canceled it is hard to rebook especially with the smaller operations. Bummer though as it can be a lot of fun if they are biting. 
    • I understand that you never really know when the Warriors are going to fall off or if they even will.  Hopefully the Wolves can make the playoffs and gain some experience, maybe teach the rest of the team how to play defense, so that in a few years we are knocking on the door and can lure in a top free agent to put us over the edge.  Its just an awful tough time to be a good team right now with the Warriors so clearly heads and shoulders above everyone else.
    • I couldn't have said it better myself pikestabber!  We have to go out there and do what we can now and not try to set up for "when the warriors are old" cuz the way the NBA is going who knows what players may join forces to set up the next "Warriors" squad.  Heck maybe the Wolves will be that next team !!  I just really love the addition of Butler and from the sounds of it we are not done yet and I am excited to see what will happen in free agency and if we could really land the likes of Kyle Lowry one of the other PG's that are hitting the FA market.  Nice to see the Wolves making moves!!
    • I would ask Getanet where to get some good ones!   Pork Belly Stinks Started by Getanet, May 1
    • So that means you ALMOST caught a fish!!   Real bummer!
    • I never use soap to clean the racks. Just put them on a hot grill for a few minutes and use a brush to get the majority off.    Hmmm, Gin flavored ham, mmmmmmmm.     
    • My local meat market will sell you one. They did for a friend of mine about a year ago. If you want to take a trip to Belle Plaine I can hook you up, but you should be able to find it at a meat market near you also.
