I am only getting 1& 1/16" of movement of the throttle cable on my 42 WLA. This is not enough (apparently) to operate the throttle from stop to stop. The carb is a brand new, surplus Linkert M-88. If I set the cable to provide wide open throttle at full counter-clockwise of the grip, the throttle plate is slightly open when I return the grip to fully closed. Is this correct? The engine has not been started yet (surplus un-numbered replacement), so I have no idea if the factory idle screw setting is correct. Both the throttle and spark advance cables have the same 1&1/16" throw. This is my first WLA project, and your collective expertise is greatly appreciated!
