Setting Pump Timing screw

THE PUMP TIMING SCREW- USUALLY THE GAP PICTURED IS ABOUT 2.6-2.8MM, BUT CAN VARY.
TURNING THE SCREW INWARDS 1/4 TO 1/2 TURN WILL DELAY THE PUMP START, BUT ALSO ENSURES THE PUMP CAN REFILL COMPLETELY WHEN THE THROTTLE IS CLOSED. IF THE PUMP CAN'T FULLY REFILL, THEN THE SQUIRT CAN BECOME TOO SHORT AND WEAK.
