Hello all... I've been having some trouble with my moped, and I was hoping there might be someone here who could diagnose my problem.
First problem with my moped was a bad air filter, and a bad float. I took the carb apart, found the float was very messed up. Ordered a new float, put it in, and cleaned out the air filter. After a little bit of messing around with the idle speed and mix (the motor kept dying when I didn't have my hand on the gas) the moped ran great. For about 2 miles.
Then suddenly, -bam-. I hear this loud firing sound coming from the muffler. Sounds kind of like backfiring, but not sure. The bike has a lot of trouble starting now. If I hold the clutch and pedal very hard for a while it starts, but it won't run right (same firing sounds), and it dies after no more than a minute.
The problem isn't the exhaust (don't know if it should have been suspect.) I removed the whole thing, and my problems were not reduced.
Anyone think they know what is going on? Did I screw something up by putting the new float in? Reading fred's guide, etc. seems to indicate I might have a problem with my points, etc, but not sure. I am no doubt getting spark, since I am hearing these firings, right? Thanks a lot.
