[weld5150]

I HAVE A 1996 YAMAHA WARRIOR 350 4 STROKE WILL ONLY RUN WITH THE CHOKE ON AND WHEN YOU GIVE IT THROTTLE IT WILL SPIT BACK THRU THE CARB.IS THIS A CARB PROBLEM OR TIMING?

sounds like you need to clean the carb

I would start by cleaning the carb. Considering the choke richens the fuel mixture, if you still have this problem after cleaning the carb, you may be jetted lean.
