Help solving mechanical issue for a newbie

[PascalGD]

Hi everyone,

I'm hoping to find some help/info on an issue I'm having with my 2015 Summit 800 T3 174 sled. It's my first sled so I don't know much about the engines but I'm trying to learn as much as I can.

Couple days ago I went out for my first day of the season. Sled was running great. Started all day on first pull. I had changed my chain case oil and tightened my chain just prior to going out. Oil was topped up. Rode for 8 hours and didn't have any issues all day. Loaded up back at the trucks and made the hour and a half drive home. When I went to unload my sled at home, it wouldn't start.

I kept trying and sometimes I could get it to start but it would putter and die right away. If I could get it to start again and gave it some gas, it would stay on but as soon as I let it idle it would die right away. It took a lot of pulls to get it to start. I tried having the throttle fully open and it would then start right away but then as soon as I would release the throttle, it would putter and die right away again.

I'm just confused as to how it was running great all day then would do this. I didn't have any crashes during the day. Not sure if it's relevant but the pull cord did seem like it wasn't right when I was trying to start it back at home. Also, not sure if it's relevant but it had been snowing all day and then raining on the drive home.

Hoping people can help out with information so I can sort this out.

Thanks in advance.

Do you have heated shop space to thaw the sled out? Do that first and try to start again. Maybe a sensor or your throttle has ice in it which can cause problems. If that doesn't do it, try new spark plugs next, could have fouled one. After that it would take more diagnosing.

swap plugs

Thanks for replying farmboy84. Unfortunately I don't have a heated shop space but it's been close to 0 in town here and the sled has been sitting in my garage so I'm hoping it has a chance to thaw out a little. I'll give it another try today then check the spark plugs.

How did you sort it out ?

I had that same sled and it died on me up on the mountain, sounded exactly like yours, and I was able to get it started limp off the mountain, although it ran like crap. I swapped out plugs and that didn’t fix it and what it ended up being was the fuel filter. Filter is an often overlooked item on those sleds, and when they go, they go.

In a pinch like that you can often remove and tap in flow side down to rattle out enough crap to flow better on the way out.

I did sort it out. Turns out it was the spark plugs. Old fuel had fouled them I guess. Swap plugs, mixed in some Seafoam and she's been running great ever since.

Turns out you were right and swapping the plugs fixed the issue. Thanks for your help.
