That is the ignitor mounted on the fender next to the coil????

How are you checking this? Keep in mind if it is a vacuum advance dist it only advances the timing when the vacuum is high (throttle closed). That is why you have to disconnect the vacuum line to the dist and plug it when you are setting the static timing at idle. Then, the only time it will advance the timing is when you are driving down the road and let off of the throttle.

If it is a vacuum retard dist (some toyotas had this) I frankly don't know how it is supposed to work or why they built them this way.

that's the set up...

added a new ground ... look like the hot wire runs through the (ingintor?) first, just a wooden dowel thingy with a coil around it? and then to the coil itself...

the only ground for this gray box is the contact to the fender, grounded it again at the screw to the - battery post.

still runs crappy, missing randomly.

I have not worked with the ignition setup that you have. I don't think the silver box is an igniter. I know it does not look like any Toyota igniter box that I have seen. With the photos up, perhaps someone will chime in with what the silver box is.

How advanced is your timing? I don't recall seeing the distributor diaphragm being behind the oil filter like yours is.

Check the gap between the electronic pickup in the distributor and the rotor too

The pick up and reluctor look like a Petronix conversion. I had one for years and it worked very well. The "silver thing" is a resistor. That simply reduces the voltage to the coil. I would suspect advance settings and, as pointed out, your distributor is rotated quite a ways counter clockwise so it's probably off a tooth or two.

do I need the resistor if I don't have points?

I have this distributor,
http://www.fjparts.com/electrical/di.../19100-AD1.gif

not this one,
http://www.fjparts.com/electrical/di.../19100-C2R.gif

which is why it looks like the diaphragm is so wacky.

So, now I realize that I have petronix ignitor which is grounded directly to the coil.

still not sure if I need to run the juice throught the resistor since there are no points. the petronix web site says to measure the volts to the coil and divide by the resitance, not sure my fluke 179 will measure the higher voltage.

I believe that is an advance distr... pulled off vacuum and sucked manually (orally?) and there is no change or movement...
could that be causing the rough running? no vac advance?
