95 Cougar 550 Tune up? - Snowmobile Forum: Your #1 Snowmobile Forum

Hi guys,
I have a 95 Cougar, and since I have owned it, it just won't idle right. Is there an idle screw somewhere on the carb? It could be the jets too, but I was thinking I would try adjusting the idle screw before I tore the carbs apart. Any help is greatly appreciated.

There are both idle screws and air screws on your carbs. Take a look at the how to part of the forum for a great tutorial on cleaning. I also wrote an explanation regarding how the carbs work, if you read that you should better understand what is ocuring in your carbs.

A tune up would be cleanning the carbs and pipe as well as replace the fuel lines!

Hey guys I am getting ready to buy the fuel lines. What size should I get?

I believe it is 1/4", but take a piece with you! And dont forget the one INside the tank! Drain the tank to below the outlet, and unscrew the tank fitting! Take it with you as well! It will need to be THAT ID and OD!

Replace the oil injection lines as well.

Next would be to go threw the clutches! The 95 is 12.2 center to center (94 was 10.2). And sand or scotch bright the sheves! Then blow them out real good!
