    Should these springs be on the carbs?

    The throttle on my 1600 is stiffer than I think it should be. Yes, I've greased the cable. I do notice that there are three return springs. There's the big circular one on the main throttle lever, but then there are also two short but stiff ones, one on each carb (see arrows). I'm wondering if these should be there. Thanks in advance.

    Thanks for that Impaw. I guess the throttle is just stiffer than I’m used to.

    Unless I'm mistaken they're the choke return springs.

    That’s what I thought, but then I wondered whether they were used considering the main throttle control spring. I’m new to Lancias, but I still think the throttle is surprisingly stiff, more so than any other old car I’ve had—which run the gammut from Aston Martin to Citroen 2CV, all with carbs.

    They are used.
    The throttle shouldnt be surprisingly stiff, it should be perfect.
    Its a Lancia
    So you have a problem somewhere.
    Something is sticking or not moving freely.

    OK, that gives me something to work on—now that I know it isnt supposed to be that way. I wonder if I may have a bend/kink in the throttle cable somewhere. Will report back. Thanks again for the help!

    Re: Should these springs be on the carbs?

    My apologies, I stand corrected, haven't looked at solexes lately as I fitted Dellorto 32 DHLA's,
    Have you checked the accelerator pedal itself? The plastic bushes behind the pedal get very sticky and swell, this causes the sort of problem you. mention, changed mine for tiny roller bearings about 15 years ago, and no problems since then.
