What would make a brand new 24" SHO engine surge? Not sure if I'm describing it correctly. It sounds like its about to run out of gas but it is full of gas. I think its fine under load but idling it sounds like it is about to cut. This is a brand new machine. It didn't do this till the last two times I have used it. I don't think I did anything differently, same gas and all.

Is this something I need to get the dealer involved in?

Thanks

I would most certainly get the dealer involved.
If you don't get satisfaction there, go to the mother ship (Ariens). Mary Lyn is on this forum and has been a big help to those that need it. PM me if you need help reaching out to her.

If it's surging or hunting try to give it a little choke and see if it settles down. If so it's running lean and might be something is loose and allowing an air leak or there is a problem with the carburetor.

If using some choke corrects the problem you could always check the mounting bolts for the carburetor and the elbow it mounts to and to the engine to make sure they are tight/snug.

It's the carb, no doubt. Possibly Ethanol gas gummed a small passage. I've had good luck with SeaFoam. Pour some in, run the engine to get the mixture in the carb and the leave it sit for a while. Will disolve gum causing blockage.

Just a thought and might be easy to verify, could you just remove your gas cap or loosen it and run the engine? Might be simply the gas cap not allowing venting enough air. If so the dealer can order one from Ariens at no cost to you.

Thanks. I tried to replicate it again today, ran it for about 10 minutes and ran perfectly. Maybe it was some "bad fuel" that had to run through the lines? When I did observed the surging, it was really cold in the teens, so maybe that has something to do with it? Next cold morning I will try it and see how it acts.

The gas cap trick is valid too. Anything that might cause it to lean out. The colder it is outside the more fuel you need for it to run smoothly so waiting for a cold morning makes sense. That's the reason for trying to cure it with using the choke. You're just making the mixture richer and if it works then we know it's a fuel/carb problem. ;)

To get a cold temp. start, you may have to do a start during the night when coldest as the forecast is calling for slightly warmer temps. Good luck

I've had the same problem on a new 28+. Thought it was the gas cap. ariens sent me a new one. Still the same problem. Have tried new fuel, Choking the engine, stabil, seafoam, non ethanol fuel, gas dry. Still the same problem. All of a sudden it will rev higher than usual, then doesn't seem to have the same toque as usual. Some time engine quits running and won't restart until sets for a while. Other times seems to work itself out and runs fine for the rest of the job. Something just aint right.

Drifty -

I reached out to our Tech Service group, and they said it sounds like the governor is icing up and sticking as this would explain the issue of higher rev and lack of power.

Your dealer would be able to better diagnose the issue as it is hard to diagnose without seeing the machine in person, so they suggested to have your dealer take a closer look at it.

Please send me a private message if I can help with this.

Thanks.

Thank you for the information. My thoughts were along the same lines(iced governor). This information from your Tech Service Group should give the local service a place to start looking.

Nope. My 28 deluxe LCT 254 runs and starts great.I,ve had plenty of experience with all makes of small engines over the years From small two strokes to 65hp v4 Wisconsins. I think the LCT is great so far we,ll see how it holds up in the long run. Hope it runs a long time
