INSPECTION
FLOAT LEVEL HEIGHT
Place the carburetor in the position shown, and measure the
distance between the float top and carburetor body when the
float just contacts the seat without compressing the valve spring.
TOOL:
Carburetor float level gauge: 07401-0010000
If the height is out of specification, replace the float and/or the
float valve. Recheck the float height.
PILOT SCREW AND LIMITER CAP REPLACEMENT
Leave the pilot screw and limiter cap in place during carburetor
cleaning. Remove only if necessary for carburetor repair.
Removal of the limiter cap requires breaking the pilot screw. A
new pilot screw and limiter cap must be installed.
Tampering is a violation of federal and California law.
1. When the limiter cap has been broken off, remove the
broken pilot screw.
2. Place the spring on the replacement pilot screw, and install it
on the carburetor.
3. Turn the pilot screw in until it is lightly seated, then turn the
screw out the required number of turns.
4. Apply Loctite
®
638 to the inside of the limiter cap, then
install the cap so the stop prevents the pilot screw from
being turned counterclockwise.
Be careful to avoid turning the pilot screw while installing the
limiter cap. The pilot screw must stay at its required setting.
