The capillary tube shows when the fuel is flowing out, thanks to its
small transparent slot.
After finding the delivery start point (when fuel stops flowing from the
capillary), press the lever and use the dial indicator to check how
many millimetres the piston has moved from the top dead centre.
Check static injection advance using the conversion table from milli-
metres to degrees.
If it is necessary to change static advance add the seals G in figure
129 (to delay) or remove the seals G in figure 129 (to advance) from
between the injection pump surface and the crankcase surface.
The same operation must be performed for each cylinder.
