B does not work on my 100mm

[elan]

My standard 100mm lens on my BL has a faulty "B". It clicks but without staying open. Apart from a clean any suggestions?. I see a Fuji 6x9 lens instruction manual online. Is a lens clean and repair a job that anybody has undertaken with the instruction book?

with thanks

If you have no experience in dealing with leaf shutters, you'd better leave this to a specialist IMHO.

Ask for a price quotation. If the repair is more than a hundred bucks, look elsewhere, as the price for a working sample of this lens is about $150 nowadays.
