when i take my hand off the throttle eithe from slowing down or accelerating it sounds unhealthy as if its gasping for air do you reckoni shoul put a polini air filter on. it sounds like a tin rattlingfor the first 3 seconds.
you messed about with the air mixture screw so that prob why.. open air filter on 50cc = bad set up and wastes petrol!
my friend was fixing my ped he fxed it today sorteed the carb etc, is the mixture screw near my back mud guard cas he was fiddling alot with that to get it working and come on facebook
