Details:

You can more easily tune these carbs to your engine make it run right, and account for any modifications you've made increase performance. Included are the long and short original throttle rods bell crank, even vacuum line. Should also mention that they idle down OK - so new shafts are not needed.FOR TR6 Owners: these carburetors can be mounted on your existing inlet manifold and used to replace the overly-complicated later ZS. NO TARIFFS!Thanks very much for your interest!, Manifold is # 305744, long-style as noted a TR4, or TR4A.

The numbers are marked on both carburetors. The whole setup is original TR4:- Carburetors are correct-spec # C1825F and C1825R, with the fixed needles mixture adjustment by a knurled knob underneath. Its a win-win for your later car!Please see photos with this listing all details of kit. All original except the screws that hold down top covers are new very nice stainless ones.

By comparison with the overly-complicated later Stromberg that have limited or zero mixture adjust ability and truly-awful temperature compensates for emissions reasons, these carburetors fixed-needle design greatly enhanced. The manifold is also the correct long or swept style. Spare parts that come with the carbs are two new diaphragms, mostly-complete gasket kits, heat insulation blocks, and four O-rings of type seal needle-adjusting screw where it passes through bottom float bowl. I've driven many hundreds of miles with these carburetors, including rallies.
