Hi folks ........... I have an M55 carb body that I am trying to fit out for my 1937EL. At present I'm a little stumped as I cannot find a referance in any parts books that I have access to over here in England for some of the parts I need. I am trying to get a parts referance number for both the main nozzle and the venturi. I do not even know if the main nozzle is the type with or without the sealing washer beneath the venturi, the body was bare when I got it. I'm coming over to Davenport at the end of the month and if anyone can help me I would be really gratefull.
