Just started driving my "project" ('73 2.0L with 74' F.I. setup) up and down the block for my preliminary road test. One thing I noticed, and my 79 yr. old father really noticed, was the gas pedal was very stiff.
I have already replaced the plastic bushings in the pedal cluster with the brass rebuild kit. Tonight, I disconnected the throttle cable from the throttle body and confirmed the cable / pedal was not the issue. It seems that the supplemental spring on the throttle body is the culprit. Is there a different, easier spring that I can install or is a stiff gas pedal just part of the normal Porsche engineering? Or, should I look for a '73 throttle body without the supplemental spring? Thanks - Scott |

Not the pedal board... either the spring is the problem or the butterfly/axle itself. |

Not the pedal board... either the spring is the problem or the butterfly/axle itself. I've got a spare 75 1.8 supplemental spring that you can have to use or compare. Is it still stiff without it? If the car has been sitting for a long time, the throttle body butterfly may have some corrosion or buildup on it that is dragging. Kevin |
