Hey guys! I am in need of some serious help with my little quad. Take a listen to the video and see if you can decipher why it is running like it is. I have yet to figure it out.

I have cleaned and rebuilt the carb with OEM parts and jets. Put in a new petcock (eliminated the vacuum port), fuel filter, and fuel line. Replaced the computer. Put on a new coil, wire, and cap. Replaced the spark plug. Checked the compression and valves. Everything was in spec with the manual. I am at a serious loss. Please let me know your thoughts.
