What size is the mixture screw?

[bigdur]

The end of my mixture screw has snapped off, I've ordered a replacement but trouble is the end is lodged in the carb, I have the carb off but cannot get it out so I think I'll have to drill it. question is what size? I have a micro bit set but I'd rather not 2nd guess!

Bit of welding wire or lockwire will usually poke it out :)

1mm should do it, drill from bottom up if that makes sense [pointy end of mix screw]

Success! That was a bit stressful lol.
