<HTML>hello again. i just got my ped back with the old 49 cc engine installed into it. problem is it stalls out unless it has a constant full throttle on. it runs and stays running with the choke on but as soon as the choke clicks off the ped sputters out without full on gas. i was playing with the idle adjustment screw but couldn't figure it out. any suggestions on how to get this fixed? </HTML>
