It should be run on 50:1
All OMCs from 1964 onwards should be run on 50:1 including those produced in 1985 and the following few years that were originally badged as 100:1.

Plug gaps have been revised to 0.030"
the latest recommended plugs are QL77JC4,
L77JC4 if suppressed plugs not required.
QL16V surface gapped plugs are also listed"
