2 part air adjuster cable adjuster and locknut to fit original Amal TT, RN and GP competition carburetters, manufactured in stainless steel, with the same profile as the original competition items
These are CNC manufactured from stainless steel with the distinctive flat top face above the knurl - only fitted to the racing carburettors. Locknut uses the correct imperial across flats dimension as the original (originals being used as the template for these).
This cable adjuster was fitted mainly to the earlier (pre mid 50's at a guess) original Ama TT and RN carb tops, that were manufactured in brass and were fitted with 3/8" diameter fine thread cable adjuster. An original adjuster and locknut is shown in the second photograph alongside our version, and was used as a template.
It should also be noted that this original type of threaded adjuster was also counterbored underneath to fit the early type straight throttle spring, as shown in the second photograph. Our versions have the same counterbore. We also sell both the parrallel type spring and the later conical type spring . . . bot types can be used with this adjuster if required.
The original adjuster was in brass and very often seized in the carb top . .. and then owners tried to remove them - invariably with a pair of pliers - so it is normal to find carbs missing these adjusters, or at least with the knurl chewed or crushed. Our versions are CNC manufactured in stainless steel, so as well as looking nice, will be stronger than the brass originals.
