Throttle Assembly
The throttle is a two-part assembly, including the rod and the cable. Install the rod first.
- Position the rod on the right side of the kart (figure A) so that the straight, threaded end can be inserted through the first frame bracket (figure B).
- With the threaded end in place, connect the other end -- which has a 90-degree bend at the end -- through the second hole in the pedal gas-pedal assembly, and secure it with the provided retaining-clip (figure C). Make certain that the concave side of the clip faces the brake pedal. The clip ensures that the rod cannot come loose from the pedal.
- At the straight, threaded end of the rod, install the spring (figure D) so that the larger diameter of the spring is facing toward the front frame bracket.
- Once the spring is in place on the rod, install the retaining nut (figure E) on the threaded end. Adjusting the location of the nut on the threaded rod will provide the ability to adjust the spring tension for precise throttle control.
- With the spring and nut installed, check the operation of the assembly by pressing on the gas pedal.
- Tip: Once the kart is operational, inspect the spring and nut regularly.
- The second main component of the throttle assembly is the cable. On one end is the bare cable, and at the other end is a cable-pull (figure F).
- Place the end with the cable-pull into the clip on the side of the engine (figure G), and insert it until the metal sleeve on the cable is secured by the clip. The metal sleeve prevents the cable from being crimped by the clip.
- Use needle-nose pliers to secure the cable-pull into the linkage on the side of the carburetor (figure H).
- With the end of the cable in place, tighten the clip using a phillips screwdriver (figure I).
- Because the cable provided with this kit is longer than necessary, the overall length of the cable is shortened by looping the cable twice, and securing the looped portion to the kart's frame using plastic zip-ties. Three ties should be sufficient to secure the cable. Tighten the ties, and snip off the excess (figure J).
- To finish installing the cable, install the plastic bushing provided into the rear frame-bracket hole, and install the cable through the bushing (figure K). The plastic bushing prevents the cable from chafing against the metal.
- Use needle-nose pliers to bend the end of the bare cable 90 degrees, and insert it into the hole at the threaded end of the rod (figure L).
- Install the cable-lock that secures the cable to the rod (figure M).
This completes the installation of the throttle assembly. In the segment that follows, the seat is installed, and the go-kart is completed and made ready for operation.
