3.6 conversion throttle linkage return
I am anew owner to a '86 930 with a 3.6 conversion, the previous owner or maybe the builder..not really sure, had a placed a return spring by the throttle linkage back by the transmission (drivers side rear area). The spring connects the linkage to a fabricated aluminum tab on the trans. It works... but not 100% of the time. It does not return correctly for that last little bit of pedal. On occasion it causes the revs to hang. Picking up on the accelerator temporary fixes this. I could try a heavier spring but I have to ask...is there a better way to make or buy a throttle return spring to do this? I've read that some people put return springs by the accelerator pedal under the floor but I am unclear how to access that area. I wasn't sure if it was a good way of doing this or if there are better ways to accomplish the same thing. I wasn't sure where to post this so I also posted this in the engine conversion section too. Thanks in advance.

My race car uses a 993 induction system.
I came up with a way to add a spring to the pivot mechanism mounted on the engine. I wanted the extra tension to be as close to the TB as possible. This works well with the combination of parts I have, and perhaps it will give you some ideas for your car.
