The switch should close at between 170 & 205 mBar absolute - if it closes at less than this or takes higher vac to close it should be regarded as faulty. The manual calls for 5 to 6" Hg and I think my math is correct but you might want to double check - knowing my mathmatical prowess
You can also check it works by means of the dynamic ignition timing but that doesn't tell you that it is in calibration of course.
169.3194 and 203.1833. close enough eh!
thanks. i will test it out as soon as i get back from orkney/parents
That is below atmospheric pressure ie 1 bar absolute - so strictly speaking it is between 830 & 795 mBar absolute if your gauge is calibrated that way
