The govenor control screw still has the lead seal on it, so the RPM is still going to be 2600 but as I say I want to check it anyway with my tacho and under load.
My workshop tacho is an optical one with a laser sight and I have found it to be very reliable. It's the same one that Joe Poulter uses for testing.
As far as the pump is concerned, my man at Lucas has put a series of punch marks on the top plate, 2 either side of the screw, in effect creating a straight line accross the screw with the slot in the screw aligned with the punch marks. At this position it is set at 19.6cc and so I can accuratly wind it out by 1/2 a turn at a time. The really important thing is not to forget how many 1/2 turns have been made or else its back to square one
I need to establish which turbo is on there, which I will do later today and then carry out some runs under load at different fuel settings to establish an optimum for my application. I'm hoping to do this at the W/E.
