Clutch return spring on Quicktime bellhousings

I would say if you have removed the over center spring for a diaphragm clutch you will need a stronger spring than the stock one to ensure the pedal fully returns.

thats what i was thinking as well

I've been running without a fork return spring for yrs.

what kind of clutch are you running? and do you still have the overcenter spring in there? i think that makes a slight difference here
