Carburettor adjustment.
Hi all I am trying to adjust the tickover on this carb/ bike . There are two adjustment screws on the side
Idle mixture and slide stop screw . I have taken this carb apart and blew out and cleaned all visible jets and galleries. Now back on bike and starts and runs ok but the tickover screw doesn't seem to be able to screw in any more to raise the speed of engine. I have bought a new slider and this does not make any difference. Can anyone think of any other things I may be missing .
Regards Neil
