I agree TMan, BUT, here's a picture of them alongside an old pair I have (which I believe are B1/B2) but could be early prewar C Series and they are same length, although slightly differant at lever end.

Haddy, what do mean by “hunting”?

Hunting to me is a drop in revs, followed by a surge in revs and repeating.  Usually when an air vane governor opens a fuel feed in a carb and overrides the throttle setting.

When the revs surge subsides the air vane opens again and repeats.

Hunting for fuel = lean or starved.

Our C bikes don’t have governors on them.   

Also, try lifting the idle.  It should be idling higher than nearly stopped.   That might be the problem.  I’m not sure why but I have a gut feeling that a slow idle bike might lean out, rev due to the lean condition, then suck more fuel/air and riches up, then subside to idle again.  That would be hunting.

From the pic those shoes look either correct, or close enough to be fettled to fit. The shoes seem concentric with the brake plate circumference, there's no disparity at the brake cam and the springs don't foul the movement.
It's not unusual for suppliers to supply linings which are too thick to allow for radius-ing. Better that than too thin.

What I do have on the shelf is two sets of B1/B2 shoes that are worn. Are these the same size as the '45 C Series? I'm thinking they are because the B1/B2 brake plates are identical to the '45?

I take it that the C10L, 11G and ohv C12 don't suffer with the end float problem?

That's correct....the points are driven directly from the camshaft, which in turn is driven by straight gears, not a worm gear, so even if there was end float in the points cam pinion, it  will not effect timing adversely.

Thats a good point Graham, worth looking at.

And...excessive end float in the distributor can cause irregular running, as timing alters as it jumps up and down, due to it being driven by a worm gear.
