NOTE:
Before removing the pilot screw 4, its setting must be deter-
mined. Slowly turn the pilot screw clockwise and count the num-
ber of turns until it is lightly seated. Make a note of how many
turns were made.
When reassembling the pilot screw, you will want to set it to its
original position.
Replace the removed O-ring with a new one to prevent
fuel leakage.

and jets. Used compressed air only.
