I have a chinese 110 cc dirtbike that is not starting. I have spark, compression, and gas is flowing through the the line and out of the carb clean and clear. When I kickstart it, sometimes it will crank and then have super high rpms for a second the turn off. Other times it will just not start. If this has happened to anyone and they know how to fix it please help.
Thanks
Update: The bike will start now but the rpms will be super high even without any throttle on full choke. It will only run on full choke and will slowly die at half choke and no choke. I bought it after it was sitting for two years... I can get a new carb, and new air filter for like 25 bucks.... should I do that and see if it helps? It is a four stroke bike and Im using non ethanol gas in it. Lastly the carb cannot be taken apart because its a pos chinese carb so I cant take it apart fully and look at the jets.

Air leaks in the intake system or gaskets at the head to cylinder and cylinder to base.
Dirty carb jets
You did not state if it's a 2 stroke or a 4 stroke engine.

Failing that, you can remove all the hoses, cables, plastic, etc. and submerge the thing (the carb, that is) in Chem Dip for a few hours, then blast it out with compressed air.

Take the carb apart and clean each jet and the carb body or buy a new carb.

Reason the thing was parked in the first place was probably because the intake valve is tight and it wouldn't idle.
Someone parked it and the carb became dirty too, tricking the tech into thinking it just needs a carb clean.
I called China, they said every one of those engines have a tight intake and exhaust valve.
