Just measured the dia of the PAW 19 carb 0.276 inchs my TT GP 10 0.331 ( the TT and OS may be the same diameter??) thats .005 difference there is enough meat on the TT to
take off .0055 inchs so it will fit. maybe some one can measure the diameter of the OS 10 and see where we are at, either is a great upgrade for the PAW

I have done this before my PAW 40 has an MVVS Carb

the asp 12 carb .353 thus 0.059 diff and thinner base not enough metal to turn left to turn down the TT carb has enough
the Enya CX11 is 0.357 and not enough thickness to take off 0.0077 martin
