Problems
once the I kickstart the engine, it’s fine, but once I take the scooter off the stand, and stop the back wheel, the engine dies. When I try kickstart on the ground it launches it forwards, rear wheel doesn’t move. If I push the moped fast enough, with the ignition on, it will start the engine. Once I push start it, I can drive it around, but once I come to a stop, the issue repeats. I feel could be a clutch issue but not sure as I haven’t done anything to the clutch apart from replace the springs, and once i did that, this issue wasn’t happening.
Older issues, Throttle stays on even when cable is fully recessed, revs right up to full throttle unless I brake. Confident this is because I have to keep the idle screw all the way in to start it then it goes, once I screw idle out, it no longer happens from memory.
IMPORTANT: Shuts off occasionally if I come to a stop, or when I go up a hill then let off the throttle on a slight flat
on downhill, engine doesn’t idle can’t hear it when let off throttle until I pull throttle then it will bog then accelerate
Weird boggy noises throughout it running
When it dies, I try kickstarting it 30 times and have to wait a minute or two before I can start it again, (now I can’t kickstart it as per the push starting issue)
(These are probably all connected issues, they have been happening since I put the bigger exhaust on, I took the new exhaust for a run and the moped died at every set of lights and I couldn’t kick start it for ages.)
Any help is appreciated.
