So I pulled both carbs, low time premiers. Both were immaculate inside including all orifices. Checked all tappets none too tight but I opened them up a thou each. Sync on the cables was decent but not great as the twist grip is likely worn afterfifty plus years. Plugs are dark, too dark. At this time of year cruise speed is low due to Our Gracious Visitors and the factthat max cruise for them is under 40. So in high gear it is 2200 to 2600. The bike is very unhappy as the throttle opening isoften barely an eight or less. So in order to get any sort of smooth running you have to run rich. But then you have darkplugs and unburned fuel. I do get the ever popular popping on a closed throttle downhill.Tomorrow will have a look at timing chain adjustment, another sad compromise on the Mighty Enfield.
