I have a few sleds, 3 of them Yamah. They are various years old, and I have never evere had a problem with them. Everey winter, they just start rite up. last year I bought a 3 seater Skidoo grand touring. after 1 season, the carbs are all gunked up. I have some time to tinker, but have never done it, and im not sure how extencive the job is, or is it as simple as taking it apart, peice by peice, and cleaning everything with carb cleaner and putting it back together if anyone has any info that would be great Thanks joshua | ||

I had 2 377E Safari Ski Doos and every year had to remove the carbs, clean and reinstall. VERY IMPORTANT. If you don't remove the main jet to clean it properly (just spray it with carb cleaner on the machine) it may run lean at 75% to full throttle. It will feel dead at top end. The cylinder away from the fan runs a touch hotter, and leaning it out will burn a hole through the piston within a few miles. Always pull the plugs after running awhile for the first time of the season to look for a chocolate brown color! If beige or tan on the cooler running cylinder (nearer fan) the hotter running cylinder will be white and you're in trouble. To richen the mixture, there is an enrichment needle that drops through the jet. No turn type screws. That's how you fine tune the color of the plugs. If you syphon the fuel at the end of season, run it dry, and fog with Sea Foam, you may get away with out pulling the carb apart each year. Once you do it, it's only a 15 minute job, and worth knowing it's clean. | ||

Carbs are usually prety simple. Like Paul mentioned, just pull it apart and clean what you can. Once you have done it a couple of times it will become routine. While I can appreciate Yamahas reliability, I cannot see that a Skidoo would be much different. The key is to drain the sucker in spring and make sure that you are not running too high of a oil/fuel ratio. Also keep in mind that while good synthetic 2-cycle oils are far better in your sled, they also tend to hang up in gas tanks and fuel lines. This can ultimately lead to a higher oil/fuel ratio and further gunk up your carb. Curtis | ||

I think his machine has an oil injection pump that injects oil into the line after carb. |
