C50 field rescue won’t start (YET!)

[Pick121]

Hi all, so I am finally working on the 1963 C50 that sat for over 20 years.
Short story is, it turns over but will not start up. It is a 283 V8 with conventional distributor. Here is what I have done so far:
Replaced Distrib cap, rotor, condenser, points (gapped to 0.19), spark plugs (gapped to 0.35), spark plug wires, all from Napa Auto Parts. I’m using a good battery from my C10. Also changed the oil and filter.
Gas is shooting out the jets into the Rochester 2G carb. Gas is clean, new, I installed a temporary tank directly to the fuel pump so as not to use old fouled gas.

Once it didn’t just fire right up like I thought it would! I put a inline spark tester, one that plugs in between the spark plug and the plug wire, no light comes on.

Anyway it got dark so I gave up for the night. Tomorrow I am trying my coil from the C10 to see if that is it or rule it out. After that maybe adjust the timing?
Any ideas would be great, thanks
