Yeehaw,Whoopie

[Nat Penton]

I installed an old Perry carb on the 91FX. It landed with the same idle speed as at takeoff. An unsuspected additional, but understandable, benefit was much better braking on the downlines. There may be slightly less top end power but the benefits far outweigh the loss, if any. The Perry has a brass barrell which has a lower coef of expansion than alum. OS needs to reengineer the FX carbs and also, I presume, the RX carbs.There may be other carb options availiable that I am not aware of ?                       Nat Penton
