Yes, the uprights must be ground to fit over the wing attach fittings. You can add another one beside what's left after it is on the wing. As for the solid plywood cap, it is not necessary and will add weight. The fabric will be glued to the piece of ply on top and bottom of the end ribs and that is enough.Barry ----- Original Message -----

I apologize in advance for the lengthy post, but I'm working on my Model-A's intake manifold and this question keeps coming up.The plans call for the removal of a wedge from the intake manifold of about 3/16" which introduces a "tilt" in the carb's "working angle" of some 7 degrees. I don't understand why. Maybe someone out there can enlighten me...I hope so. The engine was designed to go into the automobile frame with the PTO (transmission) end of the engine lower than the "front" of the engine by three degrees. The lubrication of the stock engine (largely gravity fed) was designed to function at that engine attitude. Notwithstanding the modifications that have been made to the engine's lubrication system for Pietenpol application, it makes good sense to install it in the airplane at the angle it was originally designed to operate at...which Mr. Pietenpol did. The engine bearers introduce a nose-down "tilt" of one inch in 22 inches or a little over 2.6 degrees.This being the case, it would seem that in lever flight, there would be no interest at all in inclining the carb from it's original factory position. When the airplane is resting on it's gear, however, depending upon the gear configuration, it's in a nose-high attitude of some twelve or so degrees. The way the carb is "tilted" does tend to reduce this angle somewhat, making the float sit at a more normal angle. But is this important enough to upset the mounting of the carb at cruise attitude? Without the "tilt", would a nose-high tilt of 12 degrees cause the carb to leak gas when it's on the ground? Somebody please help me out here...Thanks...Carl Vought________________________________________________________________________________Subject: RE: Pietenpol-List: Wing root ribDate: Tue, 6 Jun 2006 14:58:59 -0500
