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.

What causes this is replacement pilot valves with a differing ball weight and needing the travel modified to accommodate that.

The way Mark fixed it is the best way.
