Subject: Re: Suitable Spark Plugs for 16/80?
Many years back I was advised to always tune the carburettors on the rich side and in my experience this will occasionally give sooted plugs when left ticking over or stuck in traffic which can give a misfire but should clear once on the move
I tried several different heat range plugs on my 2 Litre and found little difference so stuck with the generally used type
If you found it was actually wet oil fouling then that may be something different..but my guess is it was sooting
