Just a follow up guys. Since doing the Nutter mod to my Jeep I have
found that the thing idles like never before, you would think this
engine had 29,000 km's on it and not 297,000 km's. Last night it
dipped to -20 Deg C here and I went out this morning pumped it twice
to set the choke and cranked it over it didn't fire up right away but
on the second crank away it went, with the computer in the loop it
would have flooded and I might still be trying to get it to go. It
does need a bit of feathering of the gas to get it to a steady idle
but I can live with that minor inconvenience.
I did notice that the sol-vac doesn't seem to respond and I was
wondering if I should bother to repair this as I thought they were
really only needed on automatic transmissions.
Any thoughts on this?

This is non-functional after the Nutter. The computer used to use that to raise
the idle at starting (~1100 for 30 sec then 900 for 2 min I think). Trash it.
I also use a CTO to control timing advance: Manifold vac <155° and ported vac
above that. Cost is $20 but well worth it. Grand Wagoneer technology.
