Spark Plugs again

26-06-2021, 08:35 PM
What are the current thoughts on 18mm plugs for the 1932 RN (Low compression head). With changes in fuel composition are NGK A6, Champion B16 plugs still the best ? After a long run, the electrodes are clean and creamy white, but the foot of the threaded section is lightly sooty. I have found that running on the 98 (premium petrol) reduces vaporisation and the engine runs better.
