Hi guys just built my bike with anbull 49cc 4 stroke kit. I could not get to start. Took off plug and it smelled like gas. Put it back and the bike started fine. Rode it for five minutes with no problem. Then it died. Now no matter which way choke it is. It starts and then dies. Even when giving it gas with throttle. I let it sit and same thing. Starts and dies. Its getting gas. Everything is new. Any ideas? Thanks
