I have too (two) many projects.
The 72 goon has a matchbox dizzy scabbed off a donor yellow 80 720 king cab (now in the junk yard). It's coli reads 9.9k primary, 1.4 secondary. (with no external resistor) I'm reading spec. to be primary8.2 - 12.4k ohms and secondary .84 - 1.2 ohms, so it is in range. I fired it up yesterday with a hose to a can of gas using my newly cut key. There was some smokeage coming off the exhaust manifold, which I tightened down later. Still not getting gas to suck up from the tank. I blew on the line that comes from the tank, before the fuel filter and it didn't seem to be blocked. Is their some juju I need to know about the evaporative tank, or do I need to try to blow out that line with compreessed air?
Then I couldn't get the ignition to shut off. Key rotated to no avail.
Meanwhile, my remaining white 1980 720 coil also reads within range: 10.7k primary, 1.1 secondary (no external resistor) Spark plug wires all read 5.5 - 6k so they are fine (less than 30k). Spark plug gaps fine. But I still can't get id to idle smoothly. It sounds like it has a hot cam then dies. I'm back to thinking that Hitachi has gotta go.
