Hi everyone, I have 8 Bing carbs in my garage, including the two on the R100GS. Not one of them has the screw anymore. I've use various rubber do-dads to seal it, but they regularly fail. It seems that it is an odd size. Anyone know what size it is, and if they might be available? I guess I could contact the Bing USA folks, but am hoping for a local solutions.
Thanks everyone.
Don

Hucky sells them for $1.10 each, and lists them as "3.5mm". Take a carb down to your local ACE Hardware metric section and look for a fine thread that fits. http://www.bmwhucky.com/007513.html

I use the protective rubber cap from prepackaged syringes. Being a Nurse, they're readily available. Once removed, they get discarded anyway.
The ones from the 'flu vax are good, as are the ones from clexane injections. Know any Nurses?

I use vacuum line caps to keep the screws clean and in the carbs.

The carb balancer makers all sell them in two sizes: 5mm and 6mm.

Mine are M3.5 x 6, pitch is 0.6 mm.
They have a small sealing washer as well and the head of the screw seems to be oversize to what you'd expect.

Re: That little screw that seals the vacuum port on my Bings
I'm not saying that this is the way to do it but I ran about 5 years with vinyl "thread protectors" ( the black ones) from Home Depot slipped over the old hose connections that remained after I removed the old emissions crap from my 82 R100. Gas didn't affect them and never had a vacuum leak.
I've since got the screws, installed them and put the thread protectors over them...additional insurance.

I love this Board! All good answers. Turns out my local 'screw' guy has 3.5mm machine screws. Going by tomorrow.
Do I know nurses? Hell ya! I love nurses- my mom, my son, 1/2 my friends are RN's. And, I work in hospitals 5-10 days a month. I'll grab some of those!
Thanks guys!
