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.

Ouch. I've not really heard anything good about HPMXs. Hard to see from the video Mark, but are both barrels on the same carb doing that? Crappy pump diaphragm?
