DB18/2 Spark Plug Gap

Post by Mark Bullen » Sat Nov 04, 2017 9:27 pm

Service data sheet 179 says 20thou, manual says 30thou. I picked the data sheet and reset all the sparkplug gaps to 20thou. They needed a good clean as a bit sooty, need to adjust the carburettor I suspect.
Anyone else spotted this gap specification difference, what should I have set please?
