Wished you lived closer mech, i had the quad running mint, and then replaced the old crappy outlet tube, now it bogs down again when you slowly push on the gas. The carb is one pain in the as* to adjust... im almost positive the float level and air fuel isnt adjusted properly. I had it running like new 3 weeks ago... grrrrr
Forgot to say as well, the old air outlet tube was barely hanging on, and more then a half in shorter then the oem one. So i replaced it, now she runs like dogsh!t again
