Ok, I have a 1985 XT-350 that has been in storage for many years and my son and I have dug it out and trying to get it running right. Carb was removed and completely cleaned and put back together, new air filter. It starts and runs great as long as the choke is out all the time. If you push the choke plunger in, it runs like crap. Pull the choke out and it comes alive. I have removed and cleaned this carb at least 4 times. Problem still there. ANy help or suggestion, Thanks
