MOPED ARMY

I think Fred's guide says possibly a points problem? I think that's probably the case.They may have went shut on you.They'll still fire sometimes,but it'll run terrible and pop and crack.Of course what Chris says is always the first thing to try because spark plugs are inexpensive and having a good spare plug with you won't be a bad idea.I've seen those flywheel keys go bad also.So start with the plug and go with Fred's Guide advice.BYE!
