<< Most Weber manifolds are tuned for 8000 RPM and up.
 Yes you will need provision for carb heat and the FAA inspector
 will not sign off your airplane unless it has carb heat. >>

Webers are (were) original equipment on the worlds most famous automobiles.
They were produced by Holley under license for Fords and Chevys until the
development of electronic fuel injection. The V12 and V-8 Ferraris and
Masserattis creeping along in Rome's traffic would suggest the Webers can be
tuned from idle to full tilt in almost any installation.
     I love my Webers, but I would not put one in an airplane. The leaning
problem aside, I don;t want a volume of fuel sloshing about up front. Also,
any negative G and the fuel is out through the bowl vent and the air cleaner
housing is, for a second or so, an unexploded bomb. The adjustable fuel
injection from Tracy seems to be a no brainer.
