    Choppy Idle - Ideas?

    Hey everyone my s2a petrol has started having a very choppy idle. Curious if anyone has any ideas. It’s been sitting about 6mo. Here is a video. Any thoughts would be greatly appreciated.


    Current: 1965 Series 2a Santana SWB.

    Is it running on all cylinders?

      Everything tightened down? (Airtight?)

      I dropped off my carb for a rebuild and when I picked it up, the old wise sage of petrol in the shop suggested to stay away from those clear plastic in-line filters as they sometimes can shed bits of plastic into the line (and the carb). He felt so strongly about it he just threw a metal cased in-line filter in the box to save me a trip.

        usually it's a air leak but you could check the vacume advance and lines?

          Check your distributor for play. If you put a timing light on the engine you will see the timing mark dancing around.
