I’m a firm believer in running your sled in the summer. I try to start mine once a month for about 2-3 minutes. This keeps sediment deposits from clogging crucial cooling areas along with keeping those seals from drying out in your engine and fuel system. Also to know is, how do you clean snowmobile carbs without taking them off? To clean a motorcycle carburetor without removing it, you’ll need to remove the bowls at the bottom of the carburetor. Once the bowls are removed, spray some carburetor cleaner up inside, wait a few minutes, then spray again to ensure coverage. Then replace the bowls and start the motorcycle to assess how it runs.How do you prime a snowmobile fuel pump?For priming the system you’ll need to take the fuel line off that goes to the fuel rail on throttle bodies. then hook up battery, pump just enough to get the pump to labor a little. There is air in the lines and this will prime the system. Put the fuel line and pump connector back on and you will be good to go.
