96 fourtrax 300fw won’t idle

I bought a project bike last night and after digging into it today, I’m not sure if I made the right move. If I can get the motor to run good then I’ll tackle the rest.

First the bike starts easily when giving it some gas. But if you leave off the gas it will die….. Every time. I pulled the carberator today and took it all apart and gave it a good cleaning, but it still does the same exact thing. Also, when you choke it, the idle screams high but will stay running. Un choke it and it dies. Any ideas?

I would really like to get this one going as I’ve owned a 98 300 2wd since new and it still runs great. Just would like a 4wd for doing some of the heavier work around the house.

Thanks
Ron
