I just took delivery of a White 65 Mustang coupe--Red interior, 200 CI with automatic trans. Everything is stock (not hot rodded). It starts every time (after a few tries) and runs well enough to drive but it misses consistently--even the timing gun light misses. It has all the typical ignition stuff replaced: plugs, points, plug wires, distro cap, rotor. Even a new Autolite 1100 carb. It had a version with an auto choke but I've swapped it for a manual (personal preference). I was kind of hoping the issue was the carb/auto choke but no change in missing issue. I've checked the mechanical timing--it's a solid 10 BTDC. Mixture is checked. Manifold vacuum 'sucks' (have not checked how much) but distro moves when I suck on the rubber tube. And, yes, it is a vacuum-rated rubber tube. Here's a picture of the Autolite.

The Distro vacuum-line comes from the carb (as shown), another V-line runs from the manifold to auto trans (I've read but I've not traced the hard-line back). A third v-line used to run from the manifold to the auto-choke so (for now) it's just plugged. Perhaps this is in error? But playing with the vacuum lines doesn't seem to affect the issue one way or the other.
The issue is that the pony--while it 'runs', is not really drivable--due to the missing--especially on acceleration. When I get a head-of-steam up, it runs but it's rough. It never stalls (as long as the idle is high enough). But when I put the trans in R or D it clunks--O or L is fine. If that's a bad sign, let me know.
>> Seems like the timing light missing (not strobing) in sync with the actual engine missing should be a clue. But pretty much all the ignition stuff is new.
Any 'informed' hunches would be appreciated.
Thanks!
