I have a '62 - 340 hp and I installed a diaphram clutch and found out the clutch peddle stayed on the floor on occasion (but not too often). I took the over centre spring off and this cured the problem. Now I want to put the spring back on and find the clutch peddle stays on the floor all the time. Is there any adjustment for this even if it helps a little? Thanks.

Re: C1 - '62 Clutch
That's why the original clutch was a fingered vs. diaphram assy. What's happening to you is the natural result of switching to a diaphram unit. They're great for driver applications, but the spring has to come off for proper operation and you'll take a deduction in a factory concours situation...- Top

I believe it can be adjusted to work properly...
...that's what the slotted adjustment hole is for on the counterbalance spring attachment location. Not very presision, but adjusting it may well help your situation. Best, Dennis- Top

Re: C1 - '62 Clutch
The original "Godzilla spring" served a dual purpose - a pedal return spring to hold the pedal up against the bumper for the first 1/3 of travel, then the Rube Goldberg "over-center" arrangement converted it to a "pedal assist" spring, to (slightly) reduce the pedal force required to disengage the original 3-finger Borg & Beck coil-spring clutch pressure plate.
Diaphragm clutches (which replaced the B&B clutch design in 1963) require far less pedal force, don't need the "pedal assist", and the spring can make the pedal hang on the floor, as you experienced.
When I restored my '57 ten years ago and installed a diaphragm clutch, I removed the Godzilla spring and the over-center bracket from the top lever of the cross-shaft after having the car judged and fabricated my own bracket from .062" aluminum that attached to the same two bolt holes, found a storm door spring at the hardware store that worked OK, painted the bracket and spring black, and anchored the bottom end of the spring to the same spot on the frame as the big spring. Functioned only as a return spring to hold the pedal up, but to a casual observer appeared similar to the original arrangement.
It would be even simpler to just use a C2 return spring from the top lever straight back to the firewall; you MUST have a return spring so you can adjust pedal free play in order to avoid frying the throwout bearing.

Re: C1 - '62 Clutch
Maybe I'm just lucky but I installed a diaphram clutch and short throw out bearing along with the factory over center spring in my 62 about 10 years ago and it works fine. It has never stuck to the floor either. I used a Ram clutch if that makes a difference. Rich- Top
