  • SU carbs

    Need a little help. I have a 1970 tr 6 ...which has been lightly modified and upgraded under the hood. My choke cable needs to be replaced. I have SU carbs. Which cable do I use. The solid one or the flexible one. According to the books and on line info. ....its the flexible one. The concern I have is the cable one took off is the solid one. I did read that if you have a return spring you can use the flexible one. Would like some feedback and some guidance. Thanks Mike

    If you have "choke" return springs on those carbs, you'll probably want the multistrand choke cable...It would have the twist and lock feature on the knob where as the solid wire does not...You might need that locking feature with return springs on the 'choke'.

        Interesting. I have a "76" with SU's and use only one choke cable connected to only one SU carb. Never a problem starting it and choke is shut down immediately after starting and I drive away.

          Even if the carbs presently use separate cables for the front&rear, you can get the linkage to connect the choke mechanisms (much like the throttle linkage. This requires only 1 cable. It is shown on SU conversion kits in the Moss catalog and should be available from Joe Curto or Burlen.

            Thanks again for all the feedback. My carbs only use one cable. It goes to the far carb. I just ordered the solid cable and now have both. Will take a go at it this weekend and this which one works the best. Does anyone know where you can purchase the locking blot nut at the end of the cable. The one they sent me...is to large for the hole. There is not much room to drill a larger hole. Any ideas? Thanks

              Check The Roadster Factory website. They usually have offerings of correct hardware.

                  I have the SU carbs so they have the nut on the bottom of the carb .....I turned it to tighten it three flats....tried one, then two and stayed with three.

                    Check that the (13) nuts (1/2 inch & 9/16th") that secure both manifolds to the engine are torqued sufficiently.
                    If some are loose, it could allow in air that would affect the mixture.
