Still having trouble with my 66cc zoombicycles 2 stroke. Bought new spark plug NGK B5HS. Same problem not firing up properly and when it finally gets going I have to pedal to keep the engine running. Got it too a point where If I kept the Engine going full throttle it would run normally and get up to speeds of about 20 km/h not as fast as usual. If I let off the throttle the engine would stall and if I engaged the clutch it would stall. After running for a while I noticed at the end of the muffler and at the top seam where I noticed oily residue was smoking even after engine was turned off. Is it possible that maybe I wasn't running it hot enough prior to when I noticed problems and oil plugged everything up.
Do I maybe just need to run it full throttle and get it hot enough to clean out the system a bit??
Has anyone ever had this problem??
Thanks
