I am a new owner of a used ys nc 120 engine. I started it tonight for the first time in my ultimate that I kit built. It ran fine while hooked up to my glow starter, once I took off the glow starter the engine dropped almost to the point of dying and ran real rough and then would eventually start running backwards and die. After it died I get fuel running out the carb. Any suggestions on what might be wrong with this motor? I was hoping to maiden tonight but it will have to be another evening.
thanks

First, fuel leaking out of the carb is an indication the regulator is not closing. Where is the regulator screw set? If it is flush with the housing or below it could be gunk in the regulator. Once this is sorted, try running it again.
