Since I don't know, are your Pro System's primary air bleeds changable? If so, it seems like tuning for part throttle would be easier there than main jets. Have you contacted Pro Systems about it?

Thanks, yes they are changeable but now I'm edging out of my limited carb skillset. I mentioned e-mailing Patrick--he is Pro Systems. He did not say anything about air bleeds, but I can call him tomorrow. Spare drillable air bleeds came with the carb.
