How to start a snowmobile at an ambient temperature below 30 degrees? I do this - slowly pouring spark plugs from the kettle with boiling water, after removing the candlesticks, watering the intake manifolds and the kick starter. Then I put the candlesticks in place and after 10-15 jerks of the starter, the snowmobile starts. Then we cover the hood for 15 minutes and you can go.
