Somehow I have managed to jam the idle mixture screw in one of my carbs. Completely stuck and will not turn even though applying enough force to twist the screwdriver blade:
Would anyone have a spare carb body?

Which type of carb is it? I have two VHB 24 and one VHB 22 BS. In Amsterdam though where i won't be til probably may...

VHBZ22HS thanks

Okay, don't have that one... :/

Someone on the forum advised trying freeze and release for a seized component. I was sceptical but it really works - not once but several times. Maybe worth a shot before you end up at eurocarb's door...

Thanks, I will try that.

If you run out of options, there is what looks to be quite a clean used pair on eBay in Italy:

I’ve bought from this seller before, no problems.

Yes I saw those, and have bought from them before. Rather more than I want to spend at the moment on a bike that does not yet start or is together yet! Thanks to Ian Lucas I have a spare carb body in the way.
