Front carb over 16 on air fuel gauge

I have an 08 teryx with Muzzy exaust, Hunterworks Carb kit with tpi valves and a cdi Set on hunterworks program. I set the carbs up 2nd clip 146 front 148 rear drilled holes and bought a air/fuel gauge the rea bung on the muzzy is around 12.5 the front bung goes straight to 16 and I guess thats as high as it goes.
I replaced the main jet with a 142 to see if it would make a difference. It didnt The air screw has no effect. Any thoughts

Got a air leak somewhere I would think. Are carbs tight and down in rubber?

Also, where is it that high at?

16 is way high or way lean, either it is getting too much air from somewhere or not enough fuel for some reason other than the jet being too small, that is not it.

Check the slide diaphragms, I have had 3 of them fail and when they fail that cylinder goes lean.

'08 Red LE, Hunterworks Carb Kit & TPI Valves, Dynatech CDI (Hunterworks Tune), Rockstar Motorsports Cage&Mirror, JetTrim Seats, Dalton Clutch Kit, Muzzy Exhaust, Muzzy cooling fan, K&N filter + outerwear, BFG KO Radials, ITP Beadlocks, HCR 6" LT kit... and I'm just getting started

Yeah that can happen, maybe the diaphragm is not in right so the slide is not working right.

Take plenum off and rev it up, see if both slides are opening.
