Do Rotax engines have mixture control?
Rotax engines have no mixture control knob. Most carbureted ones like the 912 ULS incorporate dual Bing carburetors with a high-altitude compensator that automatically adjusts the fuel/air mixture by sensing pressure altitude.
Are Can Am Rotax engines reliable?
I have used skidoo’s with rotax engines for over 15 years, they are very reliable and have never let me down. This is my first brp atv so time will tell but so far its been very reliable.
What is a too rich fuel mixture?
Last Updated on June 30, 2021. A vehicle’s fuel mixture refers to the ratio of fuel and air in the combustion process. When you have too much fuel and not enough air, your car is considered to be running “rich”. When you have too much air and not enough fuel, your vehicle is considered to be running “lean”.
What are the density factors of a Rotax engine?
Refer to the chart below to find density factors. For example: your mixture was perfectly adjusted with a 158 main jet to fly at sea level and a temperature of 20ºC, but you decide to use your engine in a region at 1500m above sea level and a temperature of 30ºC. What main jet will you need?

What kind of fuel mixture does a carburetor use?
The fuel/air mixture the carburetor provides to the engine varies with air density. Air density fluctuates with ambient temperature and altitude above sea level. It is sometimes possible to adjust the mixture by changing the position of the needle clip, but for great variations in atmospheric conditions, a change of main jet is necessary.
