Air screw difference VM29 versus VM33 30 Apr 2021 03:12 #847743

willemZ900 Topic Author Offline User Z1B 4 ever Posts: 178 Thank you received: 52	Hi all, does somebody know the difference between the air screws from the smoothbore carbs VM29 versus VM 33 ? Or is there no difference! Because the partnumbers are different! VM29 is VM26/288 002-506 VM33 is VM26/287 002-677 Willem

I always thought they were the same but never had both at the same time to compare though.
They are both available from Niche Cycle and Comparing pics they look to be the same length etc and both have the hole in the taper but part numbers prices are different and the cheaper VM29 one has the 'O' ring included.
Maybe one is fractionally longer then the other or the taper differs ?
