Bend a.026" wire gauge (T109-189) at a 90° angle approximately 1/8" from end, then open choke valve and insert gauge so that bent portion is between top of slot in piston cylinder and bottom of slot in piston (see Figure). Hold wire gauge in position and close choke valve by pressing on piston lever in choke housing until resistance is felt. Clearance between top of choke valve and wall of air horn should be as indicated in table below. To adjust, bend choke connector rod.
NOTE:
If choke shaft has a clamp type lever, loosen clamp screw and rotate lever on shaft, then tighten screw.
