Trying to trouble shoot an acceleration lean problem on this set of carbs. So we stuck the GoPro on the back and took a quick test drive. Video confirmed that the pump doesn't squirt as readily/quickly as it should. Still working out the solution, but thought I'd share the video since it's mildly interesting.

The secondary venturi and how the top is dimpled? These are EMPI HPMXs so there's all kinds of little 'things'. (IMG:style_emoticons/default/icon8.gif) |

Air correction jets that fit over the e-tubes. Are they offset like that on those carbs? Maybe it's just the angle? |
