Title: AMAC Carburettor
Post by: pulhamdown on June 28, 2010, 01:11:04 PM

Hi. I`ve got a 1927 BSA S27 with an AMAC carb.  There is a rotary knob on the offside of the carb body.  Can someone tell me what it`s for?  I can`t find any mention of it in the literature that I have.
Thanks

Colin

A photo would be helpful. The pilot jet adjustment  on the AMAC fitted to my vintage Matchless could be described as a rotary knob but maybe you are describing something else? As I said before, a photo would be helpful.Cheers,
