I seem to remember that the spec is .008 to .011. But they seem to run fine from, touching, to .020plus. Yes I've taken dizzys out with the reluctors clearly shaving the iron pole in the magnet. And I've cranked 'em out to high .020s. So I've always set mine wider, in the .011 to.013 range. That way there's almost no way that the Vcan is able to pull it into the sensor.Seems ok, as the engine revs to well past 7200 and has been doing so for a very long time,(about 11 years). I haven't checked the gap now for maybe 6 or even 8 years. I did check the timing about 3 years ago, and found it right where I set it.
BigB I sense a reluctance or hesitancy to reset the timing. What's up?
To check what the Vcan is doing, align any reluctor tooth with the sensor, and suck on the hose.If you don't have a Mighty-Vac to pull the vacuum, you won't have enough physical power to suck the Vcan to the bottom with just one suck. It will take 3 or 4 or even 5 staged sucks to getRdone. While doing this observe what is going on at the gap. As the parts inside the dizzy wear, the Vcan is often able to pull the gap tighter. A couple of thou is pretty normal. Hence why I set my gap a couple thou wider.
