Just so no one yells at me for not following my own rules.
I have a matched pair of Motobecane model 7's. They were given to me last year and I have cleaned them both up and done all the thigs sugested in Fred's "How to fix your moped".
One of them had too big a main jet so I sleeved it to the size of the small one and that seems to work ok. I also removed the stock air filter from the carb and replaced it with a larger piece of filter foam in the air box after cutting a larger hole. This solved my problem of fuel soaking the air filter.
I have one problem left. One of the peds, depending on the ambient temperature, runs about 10-15 minutes and then dies. After 10-15 minutes, it restarts and runs another 10-15 minutes befor dying. This will repeat for at least 3 cycles, I have not ridden far enough to know if it will repeat indefinitely, although it does not seem to be getting any worse.
I know it dies because the spark goes away. I also know that I do not get a spark from the end of the plug wire so it is not the plug or the plug cover. I have disconnected the kill switch at the coil to eliminate a short in that wire.
I am about to remove the flywheel and check connections in there. If anyone has seen a problem like this, I am open to sugestions.
I will post my progress anyway.
