Remove the rocker cover to expose the rockers. There should be an arrow on the flywheel which you should line up with the screw on the ignition module. This should set the piston to 'top dead centre' This is the part number for the filler guage 4180 893 6400. I believe it is a 0.10 tighten each of the two nuts on the rockers to the correct gap.
