1. For visual inspection, remove the air filter (see «Removal and installation of the air filter»).
2. Check the throttle position: with the accelerator pedal fully depressed (an assistant should do it) it should be fully open, and when the accelerator pedal is released, it must be completely closed. Otherwise, the drive needs to be adjusted.
3. Remove the spring retainer from the slot of the cable tip and by moving the tip forward in the hole of the rubber damper, ensure that the damper closes completely. If the throttle valve does not open fully, move the tip of the cable back until the throttle opens fully. Fix the end of the cable in its new position by inserting the clip into its corresponding slot.
If throttle actuator adjustment fails to achieve full throttle opening or closing or actuator sticks, replace throttle cable (see «Throttle Cable Replacement»).
4. Replace the air filter.
