My buddy just got a used mini bike off Craigslist to rip around with me on my Coleman. The guy he got it from said he just put a new predator 212 on there. It was working fine when he first got it my buddy said but when he got it to my house it wasn’t running right. It will start up fine with the choke on but every time we switch the choke off to start riding the engine sputters and stalls. Sounds like a carb to me to so we took it all apart and cleaned it. Pulled the low speed jet and cleaned that too. Still nothing. Even went ahead and got a brand new carb and installed it today but no luck. Even with a brand new carb it stalls whenever the Choke is turned off. Please help us, we want to ride!
that's good advice
