A dealer has an Ariens ST1332DLE snowblower and is listing the model number as 926028. Says it has a 13hp Briggs engine, 32 inch wide and 120V electric start. I can not find anything listing this model number. They say it is a 2008 model - brand new. Anyone have any information on this model.

I went through the carb on my 25 year old Simplicity (Allis Chalmers) this fall because I had surging similar to what you described.  I put a new carb kit in it and the surging got worse.  I was tightening the head on the Tecumseh and scratching the head on my shoulders.  It turned out there is a very small pinhole in the main jet brass nut that wasn't drilled all the way through with the new kit.  I put the old main jet back in after cleaning it and pushing an extremely small wire through the pinhole to make sure it was open.  The surging was totally gone at high speed and it idled great .  I wouldn't assume anything even though you had replaced the carb and would bet it's not set-up right (too lean) for your engine.

I found this picture which is close to the small hole on my Tecumseh.  It's hard to see when holding it in your hand.  I pushed a wire through this hole and threw the one from the carb kit in the trash.

hey friiy,

just thought l would say your info on carb adjustment/operation was prefect!! very well said. anyone with surging problems should read what friiy wrote very good info. they should post this at the top of this forum becuase l think alot people can use this infomation.

Lots of good carb information. I cleaned up a couple of old Mikuni VM28 carbs the other day. The hole in the air jet is so small that I had to use a strong magnifying glass to see if it was actually there or not. It was there and it was also plugged. The only reason I could determine that it had a hole in it was the other carb air jet was clean and I could see a very tiny hole maybe the width of two human hairs. Incredibly small. I couldn't put a wire nor a very small sewing needle through the blocked hole. I had to use a tiny drill bit to bore into the jet just a bit to clear the obstruction. I didn't bore all the way through so the stock specification hole is unchanged.

By the way, have you checked the air vent for your fuel cap?

Yes have checked the fuel cap - but will again. I did pop a hole through the screen in the fuel tank thinking this was plugged. I replaced all fuel lines, primer bulb, line to prime bulb, and fuel shut off valve as well since I was installing a new carb. I am going to look into this plugged hole in the jet also after going through the adjustment sequence that was described in an earlier message.
