Can anyone tell me if these mixture screws are the same size.
I have a set of VM28 carbs with the screws without the O ring but want to change them for the ones with.

I assume you have the carbs with the mixture screw in lower picture, if so the screw with the o ring will not fit, you either set up carbs and plug holes with anti tamper plugs or modify a set of the top picture air screws and sleeve the hole, I have recently done this myself.

Thanks for that Kev
The thing is they show both the screws on the same parts diagram, on CMSNL thats why I was asking and I found a place that sells them for 8 Euros a piece but wanted to be sure before I bought them.

I guess you are going to modify a set with the orange.
