Needle Spring

    Looking for a definitive answer.

    I am in the process of reassembling BS34 carbs. Added a small washer shim under E-clip on needle (needle in diaphragm). I cannot remember if the little spring goes below the E-Clip & Shim or above the plastic washer. I have seen various different pictures and diagrams showing the spring in both locations. No pic at the moment.

    Please help! :banghead:
  2. From the bottom:

    Thick plastic washer with centering peg, clip, metal washer, small spring, round plate, big spring, cap.

    Metal washer above the E-clip? That would defeat the purpose of it being a shim would it not?
  4. let me go check one but I am talking about the factory shim/washer, not the one you added to adjust the needle.
  5. Yes, what I listed was right. I also have the Canadian needles so they are adjustable but the order the pieces go in is the same.

    If you're adding a washer to shim it higher so the main comes on quicker then you would add your additional shim between the plastic washer and the clip but you would still use the factory washer between the clip and the little spring.

    I am all f*ckin backwards then. From bottom of needle, I had spring > shim washer > E clip > plastic washer > plastic retainer plate > circlip in the diaphragm body :doh:
  7. It's common to mess these up.
