It's magic: mixture screw disappeared!

So I was driving for about half an hour in my 5 when I suddenly noticed a very slight stuttering every now and then. No problem so far. Until I got to a roundabout... when I braked and pushed down the clutch pedal, the engine stalled. That's not normal. Fired it up again and immediately stalled again. I could only make it idle by opening the choke half way of applying lots of throttle. So I immediately thought: something's wrong with the mixture screw or idle jet. A closer look revealed that the mixture screw was just missing all of a sudden! WTF? It must have vibrated out or something... Has anyone else had this problem? Don't want this happening again, as I'm out of spare mixture screws

It can happen, more so if the mixture screw o-ring is worn or missing altogether.

You should be ok with a new one, or failing that, there are tamperproof caps available from Renault (well, they used to be available) which also stops the screw from going awol.

I always stuff a bit of kitchen roll in on top of the screw. Force it in with a small screwdriver. Never popped out again

you can restrict the mixture screw tube with a bit of sealant...dont block it or u wont be able to screw!!
