C pedal and F lever

I'm not sure if this is 'normal' or whether it's to do with the way I've got the guitar set up.
When I use the F lever (LKL) on its own, there's some movement in the C pedal. Is this usual? There's also a click when the C pedal is pressed after having used the F lever (but not with any other combination of pedals and levers). Just wondering if I've got something adjusted too tightly and wondering if there's any advice/suggestion as to how I might remedy this. Understand that the F lever is raising string 4 a semi-tone and C pedal raises same string a whole tone - is this something to do with it?
Grateful for thoughts/views on this. Guitar is an old Sho-Bud with Curnow undercarriage. Everything else pretty good, holds tune etc.

I've had this, and while I can't give you the technical terms it might be the same thing I was experiencing.
The rods under my steel have long hexagonal screw-type rods on them. I found that when I pushed the C, it was pulling the hexagonal screw bit on the C rod against the hexagonal screw on the F lever rod. Causing a clicking. Hope that makes sense!
I've done a very cowboy job for the time being and just wrapped sellotape around the C rod hexagonal screw which seems to stop it catching and allows the two rods to slide easily past each other. No doubt someone has a much more professional fix for it though. If that's even the same problem!

I can't see anything sticking, but I guess it must be somewhere to produce the click. I'll wait to see what responses there might be - I was wondering if, where you have 2 different raises/lowers on a particular string whether there was a correct order in which to adjust these - for example, adjust lowers before raises, or adjust whole tone raises before half tone raises (or vice versa, or complete bo

Nick, I sometimes got a click on my Curnow SD10. It seemed to be caused by the corner of the hex tuning nut catching momentarily on the edge of the raise/lower finger at the changer. I fixed it by putting a short, narrow circular spacer on the rod end first, just about 2-3 mm long.

Hi Will - I'll check this but the click seems definitely to be coming from under the left end of the guitar - somewhere around where the pedal rods hook up. The F lever crank seems also to produce movement in the C pedal crank and I'm not sure if the is 'normal'. Tuning doesn't seem to be affected, just the click when C lever initially depressed, and this only after having used the F lever - o0therwise, it's fine. Frustrating but not earth-shattering.

Nick - if the changes work OK, then something is catching. I don't know what sort of guitar you have (ZB type like Henry with cross-straps, an all-pull with cross-rods, pull-release or a p/p?) so the fix could be one of a few

. Examine every inch of the pulling-chain in the case; If you find nothing, then set it up and get on your back under the guitar and work the two changes separately, then together, listen and watch what moves until you can hear and see where it's from. You might need a torch.
You may well see the fix yourself, but please let's know what you find. I have no doubt there'll be plenty of suggestions!

Hi Tony - the guitar is an old Sho-Bud with Curnow undercarriage. I tried disconnecting the pulls - needless to say, without the F lever attached, the click goes away. I've re-set the pulls on C pedal, adjusted everything I can adjust and it's now... intermittent! Not sure if this is more frustrating, or whether tinkering with the various pulls will eventually cure it (or possibly bring it back full time!) Ho hum.
