TSP Switch on Holly/Webber 5200C

[One Owner 1982]

I’m looking for information on the TSP system on a Holly/Webber 5200C on my 1992 Mustang 2.3l. I think the TSP switch may be bad but I’m not sure how to test it. See attached picture. The TSP switch is on the bottom of the dashpot. Any information on how this switch works would be greatly appreciated.


I finally got this issue resolved. The TPS or Curb Idle/Stop selanoid and AC kicker. The old style was mechanical adjustable. The new style has an electric motor. My 82 was already wired for the electric motor style. Once I added a vacuum regulator selanoid it worked great!

TPS?

Yes, TPS ON AND TPS OFF. The previous picture circled the TPS switch. I’m also chasing vacuum leaks that might be hindering my adjustment.
