1985 Polaris Indy 440 power issues
Hey every one. New the the forums here and new to snowmobiles as well. I got this sled givin to me from a friend and has been a little project for me to keep busy with this winter. I did the obvious work to the engine but need some more help! I cleaned carbs, new fuel lines, new spark plugs, fresh gas, filters. Took it out after that and it wouldn't go over 5500 RPM and it was a struggle to even get it there. It had trouble just to get going as well. I would slam the throttle and half the time it wouldn't even move, would have to give it a push to get it moving. Clutch maybe? Belt? I have no idea.
Thanks for the help and happy new year!
