I am so frustrated with this moped...It ran when I bought it but as soon as I went to ride it for the second time it ran about 3 blocks then died and wouldn't start. After that it would start and only run for 30 sec then the engine revs very fast and dies. I cleaned the carb, changed the spark plug, cleaned the muffler (not with heat though), adjusted the idle speed. Then I took it to the motorcycle shop in my neighborhood, where they made fun of me for having a moped, kept my bike for 1 1/2 months, and still didn't fix the problem... They said they put in a new jet, and they put on a new fuel line (with filter). It got me half way home from the shop then died and i got to push it up these huge hills in my neighborhood...I have the manual but I'm not much of a mechanic. I want to learn but I just wish it would run so I could enjoy it a little. At the shop they said "maybe it's time for a new scooter". It still starts and then dies. I wonder if the guy I bought it from knew about the problem and wanted to unload the bike quickly. Any help is appreciated, or if anyone knows a good moped mechanic in Los Angeles.
