Supposedly, but its a bit useless on the Lucas, i'll be honest and say i can't remember which way i turned it....just turn the max fuel up about 1/2 - 3/4 of a turn to start with, and adjust the "compensator" to suit. The go back and repeat until you are happy with the tune. I found i needed to open the pump up a few times before being happy with it, and have become somewhat of an expert at getting the fuel out without spilling any, and lining the max fuel up! 
Seriously looking forward to sacking the Lucas off and getting a Bosch on mine.
