What happens if you start a Ski Doo?

If it does start on the first pull and dies, you’re pretty much screwed and it becomes a two man job. One pinning the throttle and one yanking the cord. Each sled has gone through recoil springs due to repeated starting attempts. If you guys could share your methods, I would appreciate it.

How many primers to put on a Ski Doo?

The 583’s and 670 ho’s I have owned I would give them 4-5 primers on a cold start with no problems. On a cooled start are the only times I ever had troubles. 3 WET pumps, pull it over with the throttle cracked, an additional shot or 2 once its running.

Can you start a Ski Doo with a choke?

When to start a chokeless Ski Doo snowmobile?

Cold start ( 30 degrees or below)usually the first 2 pumps are air then feels stiffer when I get gas.. 2 good pump and usually needs same baby sitting when it’s real cold with a few pumps for a minute or 2. Once it runs I’m set for the day.

Can a snowmobile shut down when out for a ride?

Two mechanics have replaced regulator twice and stator once but still does same thing. nothing worse than worrying if it will shut down when out for a ride. It takes hours to cool enough to start. Did you find the recommended reading relevant to this discussion?
