i have a question about my 95 Yamaha timberwolf it has ran pretty good all year till about 3 weeks ago when my brother was towing some kids around the house with a sled. (its snowing it Ohio) i wasn't home at the time but when i got home he was still riding it but he had been riding it the whole time (about 3 hours) with the choke on half way. when i rode it around the house just to see how it was running, cuz i didn't think it was good to ride it that long with the choke on even if it was only half way. as soon as i turned the choke off and gave it some gas it just stalled??? then it would only run with the choke on half way and it is about 3 weeks later and still will only run with the choke on. but if you run it past half throttle it will just stall. i have no clue why it is doing this and would appreciate any replys thanks,
chris

 

Did you change the plug....Running with the choke for that long will toast the plug.

 

well i put a new plug in and was jsut curious so i took off the carb adn found out that the needle snapped in half i dont know how it happened but it did so i just ordered a new k and n jet kit.
