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. N o further disassembly of the throttle body is
necessary unless the idle m ixture 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 replacem ent cap as a bare mixture screw is
sufficient to indicate that the m ixture has been readjusted.
N O TE: D ue to the close tolerance fit of the throttle
valve in the bore of the throttle body, do not remove the
throttle valve or shaft.
