applies to ALL Weber throttle shafts.
Install the new REDLINE lever on the carburetor.
CAUTION: Do not over tighten throttle shaft nut.
Proper tightness can be achieved by installing nut just
slightly more than finger-tight (finger tight then one more flat of the
nut) and bend lock tab. After tightening, open choke and check for full
throttle operation from idle stop to wide-open throttle. If any sticking
or binding occurs, loosen nut and re-tighten with reduced torque. If
excessive torque has been applied, re-centralization of the throttle
plate may be necessary. This may require loosening nut and rapping on
the end of the shaft with a small plastic mallet or a screwdriver handle
(We are not driving nails here firm, but not abusive).
