4. Cold start -thermo time switch at drivers side cam housing cover could be detached. 2 little wires. Red and yellow I think.
5. Make sure cold start valve is plugged in and pray it isn't leaking.
6. Aux Air Valve or Aux Air Regulator could be busted, but probably not.

Old Warm up regulators may wear out. If you want an adjustable one, I'll be selling mine.

Good luck.

Buy the Bosch CIS book.
I would be interested in your Brian Leask adjutable WUR for my 77 930 if it would work. Jamie
