I am not sure if I have posted here or not. I bought my first snowmobile last fall. I looked around for quite awhile trying to find one with low miles and was not a project for a low price, mostly because I did not know if I would like riding and figured I could get my money back if I decided to get out. After a trip this past weekend I think I will hang on to it for a while!

Anyway, my question is about the carbs. It looks like someone unplugged them and made a jumper of sorts for the sled side of the wiring and left the plugs from the carbs just dangle. It runs great once it warms up, but the idle seems to vary from 900 to 1300. I know it should idle higher than that, but am afraid to adjust it, since it sometimes the idle seems to wander. Also, it is a little bit of a pain when starting it from cold, I have to nurse the throttle until it warms up a little bit. I just wondered if the magnetic switch on the carbs had anything to do with this?

I planned to take the carbs off and clean them and get the idle back up to specified range, but before I do I wanted to see if there is something else I should look at.

Thanks,
Chris

Welcome to the Snow Show!
There is a great section here called the How Too section!
Clean the carbs and pay attention to the Pilot jets(up the tube), even floss it with a strand of wire! Then syc the carbs. Adjust the slides by holding the throtle wide open and adjust the cable so that the slide is flush across the bottom. Then use a 3/16 drill bit and lower the slides down onto it and loosen or tighten the idle adjuster (large thumb screw) until there is a slight drag on it! Now you can start it and adjust the idle up or down by counting the turns, keeping them the same!

I missed the how to section! Thanks for the tip. I did not think to do a search for the magnetic switches, they have no bearing on this issue seeing as they are part of the safety switch.

Hopefully I will have some time this weekend to get at this.

Thanks,
Chris

When operating properly, the switches kill the engine when the slides hang up. That can happen from carb icing or from slides that have galling that keeps them from returning normally. They can be a PITA and a lot of people disconnect them. Personally, I like the safety feature and keep mine working. Your results may vary.

Agreed. I replaced the kill switch because it was broken. Leaving the safety switches connected for sure! That 1% that it sticks and ends you in the hospital is not worth it
