Has anybody access to a Claudel Hobson HC4 carburetter manual, as used as standard on a Sopwith ABC. I have a description from the MotorCycle; however I am looking for more setup instructions on the adjustable bypass valve; which seems to be influencial from tickover to 1/2 throttle.
many thanks
Ian
