on the schematic, one of the white wires eminates from the middle of the stator, that one is not used.
black is the negative part of the voltage reg, green the output to the feild coil and brown supply to the voltage regulator.
do a compression check first to see if you have out of balance cylinders.
check valve gaps and ignition timing
next, to manually adjust the carbs, place a 2 x 2mm bits (with the carbs off) under each butterfly valve and slowly pull the throttle up. the idea is to get the bits to drop at the same height as the butterflies begin to open.
trying to suss out a paint job. Its going to be spray can but 2k hopefully.
was thinking of this rough photoshopped scheme
or may be this one
