Thank you very much for that great research
After some road testing with the "silk-boyer-special" box, at ,3" , i think it is working quite well;
but i found from the throttle response and the way the engine puts out its power,
there must be something wrong with the carb......Amal 2038/303
so i put it apart and found:
main jet: 400
idle(air)jet: 50 installed down in the float chamber instead on the carb body
choke jet: 25
throttle valve: no.3
needle: 2F1, but in highest position
spray tube: the stepped up type (Nortons!?)

....looks like i have some work to do
