RE: [DML] Re: Can someone explain this? (distributor positioning)

What Joe said is correct. If you want to see inside the CPR/ Warm up
regulator go to the link below or go to my home page and go into Bosch Warm
up regulators on the left menu bar and you can see the inside.
As Joe said, measure the resistance on the resistor on the inside with an
ohm meter across the 2 terminals and should read about 36 ohms. If you have
that then you know the resistor is good but the setting may have changed
causing it to continue to run rich. The higher the resistance say compared
to a 10 ohm means it will take longer for it to change from a WUR to a CPR
providing everything else is working alright in it.

Again I think you need to KNOW about the CPR instead of guessing about it. I
would suggest getting a CIS fuel pressure test set (John Hervey will loan
you his.) and then you will KNOW if the CPR is good or bad. Of course you
could just replace it with a new one, but having the CIS test set will also
let you have a look at such things as the dead-head pressure of the fuel
pump, control pressures, and how well the fuel system retains pressure when
shut down. (Tests the accumulator and check valve in fuel pump.)
