5. Warm the engine to 122°F.
6. THROTTLE- Completely loosen throttle friction knob and observe throttle
advance rate.
If the throttle advances rapidly to a partial position, then slowly
advances the throttle to full, the spring(s) are functioning correctly. This
may take up to 15 seconds. If the throttle is not pulled to full either the
throttle cable needs lubrication or the throttle return spring(s) or throttle
cable need to be replaced.
