Trying to fix a Turbo XS MBC, one of the new silver ones.

Can somoene who ownes one turn the dial all the way out, til it pops off the top then unscrew that brass screw shaft for me and tell me if there is an O-ring on the screw? I think this ones missing one.

Not sure on the new style ones but my old blue Turbo XS MBC has one there and this new ones not working.

Thanks.
