I am a new owner of what looks to be a less than cared for Yamoto 150cc ATV. Based on ts looks and current running condition I know I will need the help and expertise of the members of this site. I am off to find diagrams, troubleshooting, and performance advice.

 

Welcome to the forums and the guys on the Chinese quads section have had plenty of experience.

 

I have worked on the quad off and on through out the day. Not much success. trying to find the correct thread to post question. Starts fine, idles fine, low to mid throttle fine, but too fast a rev or too much throttle it bogs down and puts smoke out the pipe. It sounds like others with electric choke problems, but mine appears to be a manual choke. Carb cleaned (numerous times) all jets clear, diaphram in good shape, intake manifold in good shape, clean gas, exhaust clear, filter clean. CDI?
