Just removed the valve. Tested operation with 9v battery and it worked fine. Cleaned it out with carb cleaner anyway, and also cleaned the contacts on the valve and the plug, and replaced it.
It’s certainly working now! With the valve in place and wired up the engine idles beautifully. When I unplug it, the revs drop down noticeably.
I’ll set it up properly another day, as I don’t have time tonight to run it up to temperature. I see it’s supposed to idle at 800rpm. Any ideas how to make it do that ? Current thoughts are to run it to temp, have the idle speed lower than it should be (so the isv does its job and brings the speed up) then taking that speed as my baseline, disconnecting the isv and setting the idle to the same speed by ear.
Then I can turn on all electrics and ensure the isv functions to bring revs back to normal.
I do have an old strobe light with a red led on it that works on 4 cylinder cars with a dial to indicate the revs—you turn a knob until the led comes on and the revs are written around the dial.
It’s not at all accurate, but I could use that as an indicator only-and ignore whatever revs the dial says it is on.
Sound sensible?
