Why is my snowmobile getting too much fuel?
Could be lots of reasons. A choke stuck open, float mis-adjusted, main jet that has fallen off, lack of spark, broken skirt on a piston causing lack of complete compression are a few. Anything that causes the fuel not to be burned will contribute to unburned fuel in the exhaust.
Why is my snowmobile not getting gas?
A bad fuel pump or clogged fuel filter can keep your snowmobile from getting the fuel it needs to rev up your engine. This can cause your engine to crank, but fail to start. If it’s been over a year since you last replaced your fuel filter, replace the filter and try your snowmobile’s engine again.
What would cause a snowmobile to backfire?
A snowmobile backfires when it runs on a rich or lean. It means the ratio of fuel and air is not balanced. When this unbalanced fuel mixture is supplied to the engine, the combustion does not happen properly. This uncombusted mixture reaches exhaust and burns there, which causes it to backfire.
Why is my snowmobile smoke so much?
Your snowmobile may smoke some when it’s in idle or during startup, but when the smoke gets to the point where it’s choking you, it’s too much. The problem could be due to coolant leaks in the cylinder, a faulty oil injection pump, old fuel, or heavy parts in the fuel clogging up the crankcase.

How do you test a snowmobile fuel pump?
To test the fuel pump, I remove the fuel line from one of the carbs and stick the line in a clear plastic bottle. Then I pull the rope a few times. There should be some gas spurt into the bottle on every pull of the rope. If there’s NO gas, you have an issue.
What has spark and fuel no start snowmobile?
One way to fix this is by turning the motor over with the choke off and spark plug out until all of the fuel has dissipated. Clean the plug and put it back in. If your sled floods out immediately or if it is not getting fuel to the combustion chamber, it is time to either clean or rebuild you carbs.
What are the symptoms of a bad stator on a snowmobile?
Runs bad at lower rpms but runs good at higher rpms (Low speed coil going bad) Runs good at lower rpms but runs bad at higher rpms (High speed coil is going bad) Backfiring and just won’t run good. Sled slowly loses power during the course of the day.
What causes a two stroke to backfire?
The most common cause for a two-stroke backfire is because of rapid deceleration of the mower. This allows too much air to enter the engine causing the revolution to be thrown off. Deceleration is not the only reason for a two-stroke mower to backfire.
How do you start a snowmobile after sitting for years?
Do snowmobiles smoke a lot?
the sled should smoke a lot if it hasnt been started in a while or it has stable in the fuel. A good idea is that if the sled smokes a lot when first started but slowly goes away thats good, it when its not smoking a lot you need to start worring. You’d rather have too much oil than too little.
