My carb Citroën BX interior rattles on idle. This mostly happens before the engine warms up, as soon as I apply the smallest amount of throttle this disappears, which leads me to apply throttle when stopped at lights or keep my choke activated for nllonger than usual.

Here's a video reference https://youtu.be/ry84LsLrOuA The sound is louder on the recording


It may indicate that either you need to wait a while to put the choke in or that you need the idle screw adjusted on your carburetor.

  • How would I know wich is the solution? I'm guessing it's not the choke since my car doesn't struggle to start after I stop, but I'm just guessing. What's the recomended way to use a choke? – EChan42 Apr 21 '16 at 11:44

    Use the choke until the car warms up properly. You can reduce the amount of choke gradually until it's fully off and keep the car running smooth. – Steve Matthews Apr 21 '16 at 12:47
  • I'll take that in to account. Shame I can just guess since my car doesn't have a temp gauge. – EChan42 Apr 21 '16 at 13:31
