1992 Arctic Cat Jag 440 FC
So recently I got the sled from my fathers and brought it home. it had been sitting for 2 years. Prior to sitting it ran like a total champ absolutely no problem. When I get it it barely starts. I drained the fulel lines/tank. I also took the carb off and cleaned everything throughly. From there I put it back in with 93 Octane gas. I pulled her 5 times and she started up and stayed running.
She idles fine. Has horrible take off power... It'll just bog and won't go up hills. after moving 5 miles an hour the power increases greatly for 30% of throttle then it plateaus off.
When idling she is smoking pretty bad and you can smell richness of gas.
The carb on this has 2 screws located on the pullstart side. A big screw with an external spring/screw. I believe thats for the idler. Then to the left of that or closer to steering wheel there is a smaller screw with an internal spring. I have no idea what that controls.
My question is this. I havren't replaced the plugs but I can that I am getting spark.
My suggestions that could be it are vaccum leak (is this possible?) My idler screw is not adjust right or the other "unknown" jet is not adjusted right. I lso think it could be the choke cable going to Carb. This does not have butterfly's.
So can someone give me some hints or tips to tackle. After work today I am getting spark plugs and will try that and limit that its not the plugs. From there I am going to pay ith the jets.
