How to Install a Throttle Cable into a Koso Slide Carburetor

Introduction:

This guide will instruct you on how to install a throttle cable into a Koso slide carburetor. This carburetor requires a different style throttle cable than is normally found on a stock buggy. You can purchase the correct throttle cable for the Koso carburetor from Buggy Parts NW by clicking this link.

This how-to guide works for all Koso slide carburetors that BPNW offers.

Tools:

Philips Screwdriver or metric Allen wrench.

(Note: In the images in this tutorial, we have replaced the philips-head screws with socket head screws for easier access and removal. You can purchase these screws for your carburetor here.)
