recently bought a 2 stroke 50cc super bike for $30 off of a friend, the bike looks to be in good shape. only problem is i can only get the bike to start with "QUICK START" then the bike will die after about 5-20 seconds.
ive cleaned the carb, and have tried multiple carbs, the plug has spark, fresh 94 octane gas and oil.
-i think the problem may be the carbs. one of them will not prime and has tiny air bubbles in the primer and sends air through the fuel line.
-the other one leaks gas from where the bubble mounts to the carb when you prime it.

how can i fix these carb problems and what can i try to do to get the bike running

your bike has two carbs?

I think he means he changed carbs back and forth, something I have become real good at,lol.

Lol I dont need to change em, it takes me about 10-15 minutes to remove clean and remount my carb... I like to keep it clean so I get the most out of my motor

yea i switched carbs back and forth. do you guys have any idea what could be causing the problems?

leaky primer bulb on the first one... a walbro wt603 repair kit would fix that.

Well I got the bike running 1-2 times and then I shut it off and it won't start again, the carb is leaking quite a bit of gas from the wholes on the bottom of the carb. Any ideas?

Sounds like you have a 49cc piston port engine.
