My Leblanc LL200 plays at least 20 cents when using the supplied 66mm barrel. Still flat with my 65mm Backun. The flatest note being clarion C. How do you know when bore/tone hole work is needed, or just a shorter barrel. If it plays so flat why was it sold with a 66mm barrel? I would love to send it to Morrie Backun for work but that is not likely possible. Who does bore/tone hole work in California.
Thank you for any replies.

you don't have a Vandoren "13" series mouthpiece, do you?
(these are made to bring the pitch down on R13 clarinets and might play way flat on other makes)

The Smith is a custom mouthpiece that does tend lower (I'm not sure about the Fobes).
Are you sure you have an actual L200 barrel? I seem to recall Leblanc making some whoopdeedoo at the time about this clarinet and it's unique bore. I'd make sure you have the right barrel first.

Bore reaming is a risky procedure that carries absolutely no guarantee of a good result and can destroy the instrument if it doesn't fix it. If this isn't a very old instrument, its bore dimensions are unlikely to be so far out of spec that the clarinet's pitch is affected as much as you're describing.
Tone hole work is generally useful when a particular note is out of tune with the scale around it. If the problem is with overall pitch, this isn't an effective remedy.
Your best bet at getting the general pitch better is to find a barrel that works. I don't know anything about the design of the LL200, but if Paul is right in his recollection, check into whether the "supplied" barrel is the right one. As the barrel gets shorter, the throat notes will come up the fastest. If you can get the pitch of the longer notes to be generally at a good pitch level, sharp throat notes can be tuned by putting material (tape, putty, lacquer) into the top of the tone holes that produce those notes. But you have to get the overall pitch up first.

It's not even length, I think the bore was quite a bit narrower. A barrel with a bore that is too large might cause tuning issues as you describe.

It could be also the socket/tenon mismatch. Some barrels/MPCs/joints do not really match, I've seen 1.6mm+ gaps btw top of mouthpiece tenon and bottom of barrel socket. Gap like this would make it flat, with some tones more then others.
Have it checked and fix with tuning rings good luck
