I just finished building a 48cc gas bike kit on a old mountain bike. I can get it to start but if I give it gas or slow down it will die. Also just dies when I pull the clutch in as I'm slowing down. Got it to idle and somewhat take throttle barely once but not sure what it wants or how to get it there. Guessing its the fuel/ air adjustment but gets exhausting peddling this heavy thing to dump the clutch to try and start. Any tricks or tips to get these going and tuned for the first time?
