Hi RobSS, Although AMC took over in 1953 they were not producing Nortons at the AMC facility untill the Norton factory closed around 63 , Once AMC took over production they started to change all sorts of things from threads to finishes .I have bikes from both factories but only really regard The Norton Birmingham produced bike as a "proper " Norton . A sort of snobbery!. I am interested in the Ewarts flow experiments as I have had an odd experience of Running out of fuel on main, turning on the reserve and finding it all gone tank dry. As the tap filter and standpipe are intact I can only assume that the fuel reserve can seep through the main tap workings at just enough rate to keep my 99 ticking along ( one was tested to over 100mpg !!). Going to fit my spare Ewarts to the Atlas to replace the modern leaky tap. Have to warn son about the non reserve reserve!.
