tle cable bracket from carburetor top. Remove gold Phil-

tor top from body.

DISASSEMBLY - BOTTOM END
1. Turn carburetor upside down and remove four Phillips
screws loosely installed at bottom. Remove float bowl
from carburetor body.
IMPORTANT NOTE
Tapping the float pin out from the squared pedestal side
will result in damage that requires carburetor replace-
ment.
2. See Figure 4-12. Using a small center punch and ham-
mer, carefully tap float pin from holes in pedestals. The
rounded pedestal has an interference fit to ensure that
the float pin is securely held, so always tap out the pin in
the direction of the cast-in arrow (that is, from the inter-
ference side).
