Hey guys I'm having some trouble with my dirt bike. When I bought from the previous owner it ran fine and started many times. Then my friend was riding it and when he was coming to a stop either he stalled it or it shut off on him while moving. Now it won't start. I took out carburetor and its clean. I took out the spark plug and it has a spark. We jump started it and let it idle for a while and then tried a kickstart and it worked. Then it stalled again coming to a stop and won't start again. What can the problem be? One thing I noticed is the carburetor has about 4 or 5 hoses coming out of it going to nothing. Are they all meant to be overflows or do a couple of them go somewhere else?
