* Engine Variation: Even within the same model year and horsepower, there can be variations in engine design that affect the ideal fuel mixture.
* Fuel Type: The recommended fuel mixture can change depending on the type of fuel being used (regular gasoline, premium gasoline, etc.).
* Operating Conditions: The ideal fuel mixture can also be influenced by factors like altitude, temperature, and engine load.
Where to Find the Correct Fuel Mixture:
1. Owner's Manual: The most reliable source of information is your snowmobile's owner's manual. It should have a specific section dedicated to fuel specifications.
2. Service Manual: A service manual for your specific engine model can provide detailed information on fuel mixtures and other maintenance procedures.
3. Johnson (BRP) Website: Check the website of BRP (Bombardier Recreational Products), the parent company of Johnson. You may be able to find information specific to your model year and engine.
4. Local Dealer: Contact a reputable Johnson dealer in your area. They can provide specific advice on fuel mixtures for your model.
Important Note: Always use a high-quality gasoline designed for small engines and follow the recommended fuel mixture ratio precisely. Using the incorrect mixture can damage your engine and lead to costly repairs.
