The carburettor is an 1 3/32" Amal TT. It has been bored to take an oversize slide, and I have a spare oversize slide. I have fitted a Tufnol spacer with a polished aluminium sleeve between the carb and the head. Carb settings are: Main Jet 360, Needle Jet 109, Needle Position 3, Throttle Slide Cutaway 6.
