SUBJECT: Self tapping screw part #309650 for
carburetor float hinges - all V-50
and V-75 engines.
One cause of flooding not to be overlooked in carburetion diagnosis on V-50 h.p. and V-75 h.p. engines is a loose float hinge.
Those who have already experienced this problem will be glad to know that a self tapping screw is now available to correct this condition in the field. This item is being made available since resecuring the float hinge with the original drive-screw, part #160089, will not prevent the reoccurrence of this problem.
The new self tapping screw is available as part #309650 at $ .03 list through your Parts Distributor. We suggest that you keep several of these on hand so that repair jobs of this nature can be expedited without delay. Two screws are required for each float hinge.
INSTRUCTIONS FOR USE OF #309650 SELF TAPPING SCREW IN
ALL 50 H.P. AND V-75 H.P. ENGINES.
The new self tapping screw is larger in diameter than the drivescrew. It will therefore be necessary to enlarge the two holes in both float hinge and carburetor cover.
- Remove carburetor float, float valve and float valve seat.
- Use a narrow file - to carefully file the head off each drivescrew.
- After drivescrew heads are removed - lift hinge off drivescrews.
- Grasp drivescrews securely with vise grip type pliers and carefully remove each screw from the carburetor cover by turning counter clockwise. CAUTION: Work carefully so as not to break drivescrews off with plier.
