Explanation of FKA carb rule:
All of the technical measurements and No Go's on the flathead carburetor still apply, However, We have done away with the ridiculous "Finger Check" on the eyebrow or transfer edge in the airhorn. Everybody since day one ( even passes wka tech ) has been deburring the transition edge on a 5 hp BS carburetor with a slight message! We don't throw anybody out on a finger check but when I look down in the carburetor air horn I don't need to be able to determine you've been working in there! Yes, if the 1.011 no go sticks from the bottom it will be wrong.
Thanks for reading.
See you at the races.
