Putting together a set of BS34's for my run stand. Both idle mix screws are missing the washer and one is missing the spring.
Anyone holding?


Bueller.... ?

Just in case someone has loose carb parts...
Spring is a hair over 9mm long.

I'm guestimating the washers are 5mm OD and 3mmID.

I don’t have any extra but mikes xs sells an air fuel mix screw set; which includes a needle, spring, washer, and o-ring. The needle is tapered so it is richer and usually set at about 1 turn out. I haven’t bought one before but niche cycle on eBay also has a set.

Let me see if I can find my set of 33mm from the XJ and I'll see if they're the same.
