93 XT350 running problems
I am hoping someone can help me out. i have a 93 XT 350 in which I can get started with choke fully out. It runs at high rpms, but when I take the choke off the bike dies. When I start it again on full choke, I can back the choke off to about half way and it runs about 2500 rpms, but pops and backfires. When it idles at this rpms the revs go up and down still popping and backfiring. No matter how long I run it it will not idle with the choke off.
Just curious if anyone has had this problem? If so, how did you solve it? Can it be the mixture screw that needs to be adjusted. I am wary of doing this since they seem to say it was set in the factory 17 years ago. The bike did sit in the summer in a barn and somehow all the fuel either evaporated or drained out. I am open to any and all suggestions!
Thanks for your help!
