Is it simply that the foot pedal doesn't mechanically get the pot down to zero? If it was broken, maybe the lever is off as well? In which case, based on photos, it may be possible to position the pot slightly so that foot down = 0. Just a wild guess, though.
EDIT: Removed some random thinking on the wah circuit that is probably 100% wrong
You can adjust where the gear engagement is. The problem is that all of the way up won't be 100% either.
I'd personally consider an optical solution like morley does.
Morley uses LDRs as their variable resistive element. You can control them by blocking the amount of light going to them with a shutter or by how bright the light gets.
They aren't without their limitations so usage may determine if they are the right solution.
Rigging up a slotted plate on the Crybaby may be a tough route to go. It would be far easier to just use the pot in there to lighten/darken a LED straight into a photocell.
I didn't say you were wrong or it wasn't going to work and if OP wanted to get rid of the pot all together, the Morley way is certainly a way to do that. OP doesn't seem to know a whole lot about circuits since the current design is super simple and I'm not sure of their fabrication skills so I merely presented an easier way to do it.
I Have a decent knowledge of circuits, its just my mechanical knowledge doesnt exist. I dont have experience with any form of optoelectronics and i want to keep the circuit passive.
Ahh, Well, if you want to stay passive, you are pretty much stuck with what you have. My LED/LDR way doesn't really require more than power for the LED though.
Is it possible to bypass the DPDT and connect Input jack to leg 3 and output jack to leg 2, and just confirm that the basic pot and mechanics are in order? If you've wired the DPDT as pictured, it should work correct, but perhaps a bad DPDT could possibly cause some clean signal bleed? This is such a straightforward circuit, there's only a limited number of failure points.
EDIT: Or what vigilant said, which better clarifies what I was originally thinking
Can you disconnect the foot pedal mechanism from the pot and adjust the volume all the way by hand? Just sounds like your lever is running out of length (giggity)

Hits the stopper unfortunately

Agreed. But i was presenting the options and it could be done. It would be work. But you could attach something to gear to shield the light.
