Why does my snowmobile smoke so bad?
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 often should you check your snowmobile spark plug?
Keep your snowmobile in top performing condition by changing out your spark plugs on a regular basis. For moderate snowmobile use, one set of spark plugs per season is sufficient. If you’re riding hard and often, be prepared to change out your spark plugs more frequently.
Why does my snowmobile not have a spark?
A weak plug may be able to spark in the open, but will not under the compression of the cylinder. Fortunately, most spark plugs are inexpensive. If you still do not have spark after installing new spark plugs, then you have an issue with your electrical system. You will need to check your plug caps and wires, coils, cdi box and rectifier/regulator.
What to do when your snowmobile won’t start?
If you are getting spark, you will be able to see it. If you do not get any spark or are getting a very weak spark, it is time to change your plugs. A weak plug may be able to spark in the open, but will not under the compression of the cylinder. Fortunately, most spark plugs are inexpensive.
Why do I have smoke coming out of my snowmobile?
If there isn’t, do you think any of the crank seals could be leaking or maybe those check valves where the small oil lines off of the oil pump connect to, could be stuck open? If there are no leaks then I might pull it back out and I will pull the jugs off and send a couple of pics in for you to look at.
What do you need to know about snowmobile engines?
Your snowmobile engine needs three things to run- Spark, Air and Fuel. If you’re not getting the proper amounts of any of these three, your sled is not going to fire properly. Of course, your engine needs to have spark to ignite the air/fuel mixture to start. The first place that you should check is the spark plugs.
Is it normal for a snowmobile engine to smoke?
First, let’s make one thing clear: more than likely, your snowmobile is going to produce smoke from time to time. Like we said in the intro, this is indeed normal. If you see some smoke behind you (as it’s typically coming from your engine or gas tank) but the smoke isn’t getting in the way of your ride, then you’re okay.
What does white smoke mean on a snowmobile?
White smoke is usually indicative of anti-freeze getting into the cylinder/s and getting burned. It doesn’t sound like a fuel issue. In what manner did you check your oil pump? Does the smoke clear up after you are running at speed?
