Did you set the output of the accelerator pumps to .25cc - .3cc for every pump stroke?

I got a free, small plastic syringe vial from a local pharmacy, wrapped a bent paper clip around it as a holder so I couldn't lose it and then put it down into the throat to capture the fuel coming out of the accel jet on each throttle stroke. Cranking the accel pump adjuster nut IN makes more gas out the jet.

Another thing it could be is the floats set too low but, again, all this stuff is apparent once the carb whisperer hooks up a wideband analyzer and says "Ah-HA!" We've all tried to be arm-chair distant analyzers on here in the past and seldom got it right, except when Stan says that "90% of carb problems are caused by ignition".
