Pocket bike engine won't stay running.

Hey guys, What's up?

Ok I have a little problem with my pocket bike here. It's a 49cc bike that I just got about 3 weeks ago and it was working fine until last week. All of sudden when I tried to start it one day the chain pull start got really hard to pull and it wouldn't start. I was like okay, I'll try again tomorrow.

So then I tried it again, this time the chain was alright and normal, I got the bike to start up and all and choke on position, and then I put the choke off and Im off to ride the bike BUT
*The bike stops after you give it too much gas or not enough, the engine just dies on me right in the middle. I dont know whats wrong with the bike, I've been taking good care of it and everything.

PLEASE HELP ME???!!!

How can I keep my bike running smoothly and so it wont die on me?
Thanks.

Is your idle properly adjusted and set?

^^^ What do you mean by idle?

The screw with the spring on it that's on the carb. Turn the screw, try and start the bike to see if it idles, if not, keep adjusting until it does

can you take a picture for me?

lol

i dont see it...my bike is a Rossini cag.

moved to cag forum

um... sorry I don't have a pic handy, but look a little harder and you'll see it lol

your idle should be on the left side of the carb right in the middle. usually it is a gold color with spring.

Your gasline probobly has a pinced hose somewhere. This happened to me.

the idle is a little screw by the carb or if it keeps dyin when u stop givin it gas it could be ur exhaust letting in to much air so tighten that if nothin else works

ur engin might be shot or piston may have blew take off the pulley part and try spinning the rotor by hand if it doesnt spin smoothly somethign is dragging

found the idle screw.

fixed the problem...


thanks!!!! appreciate it.

Im having the same problem except, when i put the bike on the stand and wot its fine. is it the same problem with the carb?
