Throttle Body (Fig. 6C-12)
1. Invert carburetor bowl on bench and remove two
throttle body to bowl attaching screws. Throttle body and
insulator gasket may now be removed.
2. No further disassembly of the throttle body is
necessary unless the idle mixture needle is damaged or the
idle channels need cleaning. If necessary to remove the idle
mixture needle, cut the tang from the plastic limiter cap. Do
not install a replacement cap as a bare mixture screw is
sufficient to indicate that the m ixture has been readjusted.
NOTE: Due to the close tolerance fit of the throttle
valve in the bore of the throttle body, do not remove the
throttle valve or shaft.
