FUEL SYSTEM
FLOAT VALVE
Check the float valve and its seat [1] for wear or
contamination.
Check the valve seat [2] for clogs.
Before installation, check for wear or a weak float valve
spring [3].
Check the operation of the float valve.
PILOT SCREW REPLACEMENT
Leave the pilot screw [1] and limiter cap [2] 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.
When the limiter cap has been broken off, remove the
broken pilot screw.
Place the spring on the replacement pilot screw, and
install it on the carburetor.
Turn the pilot screw in until it is lightly seated and then
turn the screw out the required number of turns.
Refer to the table above for carburetor pilot screw initial
opening setting.
Apply LOCTITE® 638 or equivalent to the inside of the
limiter cap and 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.
