....................... checked the timing with the engine idling and the notch in the pulley lined up with the TDC arrow on the casing. As I revved as per the graph in the Haynes manual I checked that the notch moved to the 10 degs point on the housing and this was correct. Alternatively I adjusted the strobe light to 10 Degs on the rotary knob and did the same and the notch on the pulley moved to the TDC arrow, which is also correct. I had a multimeter connected to the No1 HT lead to read REVs.
I then revved the engine to approx 3000 rpm and I set the strobe light to 18 DEGS on the rotary knob as the engine RPM increased the notch on the pulley moved to the TDC arrow and was only slightly off. I rotated the Distributor ever so slightly to align the arrow with the notch on the pulley with the strobe gun set to 18 Degs and 3000 rpm.
The clamp nut on the distributor was tightened, it appears to be running ok.
