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 |

initial pedal resistance goes back to the throttle plate getting stuck in my expereince.
there is a build up of invisible laquer that can occur...not sure it is laquer..there is just air going through it... BUT Dunk the throttle body in carb cleaner for a long period...it will get even smoother. Cant see it, but the plate does stick a bit if there is a build up. You can feel it on a taken apart TB...just the body, shaft and plate. No springs, no TPS.... It should flop around, never getting stuck when you just shake it. If not, sumpin is up. Rich |
