3. Stop the engine.
4. Remove the flywheel cover or recoil starter.
5. Operate the throttle control grip (or throttle lever) to bring
the throttle to full open position.
6. Return the throttle gradually while watching the tip of the
dashpot unit rod. The dashpot rod tip must contact the ac-
celerator pump lever at the same time the No 3 carburetor
idle adjust screw contacts the throttle stop.
7. If these two contacts do not occur at the same time, adjust
the dashpot unit rod in or out as necessary.

8. To reset engine idle speed, return the No.3 carburetor idle
adjust screw to its original position (i.e. the number of turns
counted in step 2).
9. Install the flywheel cover or recoil starter.
10. Start the engine and, if necessary, adjust engine rpm to
the specified in-gear idle speed.
11. As a final check of proper adjustment, shift into forward
gear and quickly decelerate to full closed throttle from sev-
eral different throttle positions, checking the dashpot's ability
to provide a controlled return to idle speed each time the
throttle is closed.
