| 9. | Adjust pushrods. a. Adjust pushrod length to zero clearance by hand. b. With pushrod adjusting screw kept from rotating with a wrench, slowly turn pushrod tube with a wrench, 2-1/2 complete turns clockwise (lengthening the pushrod) as viewed from bottom. (There is a dot on the flats of the pushrod tube that can be used as a reference.) c. Hold adjusting screw and tighten locknut with wrench against pushrod tube.
