Help my Lifan 125 has extreem high revs. Its the carby as this happened to the last motor I tried it on but I don't know what. I have tried adjusting the needle setting, idle screw and fuel mixture srew but it does not seem to help. Slide is put in right and I have full throttle movement. Idle screw is right out and it does not stop high reving. High revs are completly consistant with no ups and downs. I can rev engine higher with throttle but it does not come down. Any advice welcome. Ps all seals are ok.
