I've got a 350 TBI swapped into a truck originally carb'd. I found the pedal pressure to be excessive, so somewhere along the line I clipped one of the return springs. I like the feel of it with a light pedal, but it also seems mildly hazardous. Having redundant springs seems like a good idea for safety. I was wondering if there exists lighter springs I could install so I could have both of them with the lighter feel. Also, how painful is it to replace them? I've never had the shaft out, not sure what's involved. Thanks.
