Ariel Owners Motorcycle Club

I am changing the carb on my 1951 VB from the original 276 carb with the separate float chamber over to the 376 monobloc. (The reason is that the 276 carb leaks fuel incontinently) I have a 1 inch bore Monobloc and I am jetting it to suit the VB. The Draganfly website lists the jet sizes, but I am slightly suspicious of the main jet they are specifying, which is a 220. The old 276 has a main jet of 160, and it seems a big jump in size. Does anyone have a riders handbook for the later VB which shows the monobloc jet sizes? Thanks Bob

Roy bacon book post war models also list 220 main jet when using a 376 carb

The Draganfly listing is taken from official docs such as Owner's guides that are all available to download form the club website for members.

Thanks Dave and Roger, that's perfect. I'm sorry to have doubted the Draganfly website!!
