Pilot Screw Replacement - Honda GX240RT2 Service And Repair Manual

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, then turn
the screw out the required number of turns.

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.
