I recently purchased a Chinese MC-54-250 and experienced similar problems with starting up and noises, rattles, and now I cannot start the engine. This is not even registered yet, less than 50 miles on the scooter! I found the idle speed screw by looking at the carberator and turning the throttle - I also set the idle speed to 18k to 20k RPM. Thought that I had everything fixed until I took for a test ride and the engine stalled. Now it will not start - I am wondering if the idle speed screw and the fuel mixture screw (mentioned in a previous message) are the same thing. Is there a seperate fuel ratio screw? if yes, can someone help me out where I find that? -- thanks -- and I too am new to the site and to scooters.
