Snowmobile has no middle speed - Snowmobile Forum: Your #1 Snowmobile Forum

Its either slow or all the way full throttle. At top speeds it runs great but I turn a corner and its bogs, then accelerating is rough bogging. Then I get the throttle all the way to the bar and the high speed kicks in and then it runs good... until I slow down again.

Any help is appreciated!

I would start with cleanning all the jets in the carb. Then sinck them. Then clean the clutches and check the center to centers. And wirth a new belt I would get it as tight as possible!

The carbs are as clean as can be and i cant really see what is goin on with the belt when drivin, i dont really want to mess with that. I dought it is the belt because it is bogging

Check your boots for an air leak. Sounds like you have a vacuum leak some where that's why it bogging.

Sucking in air causing a bog. Until wide open throttle were it not effecting the air to gas ratio!

Mesure the center to center on the clutches, and then put a carpenters square across the plugs to the driven!

This sounds like it could be influencing the situation. My boots are cracked and there is sealer on the sides of them but I should probably add more. It has been a long time since the sealer was put on. Thank you

Replace them.

yes, replace them. they are not expensive! if it is still too lean adjust the air screws!
