Recently bought my 5 yr old a pw50. It ran but never like it was supposed to. Constantly fouling plugs & it would barely idle. Guy I bought it from said he always had to clean the carb. My son was riding one day & went to turn around & it died. Took it home replaced plug & it started for about 30 secs then died. Wouldn't start again. Got tired of cleaning so I bought a new one. Put new carb & it fired right up. Had throttle slide 180 off so it was full throttle all the time. Fixed that issue & it hasn't started since. Put new plug again & noticed the plug wire was broke & cap would pull right off of wire. Bought new coil. Still won't start. New carb, new coil, new plug!!!! Is it the reeds??? Any help would be much appreciated!
