Timing with the stock wires requires an adapter to hook a timing light to OR a modified spark plug wire to hold a standard style spark plug and then allow a standard timing light to connect to it...
I did it this way:
Get a length of standard plug wire...strip down to the inner wire on the NON spark plug end...take off the #1 shielded wire (thats the stock military wire) and put this wire you made above in its place with the stripped part shoved down the hole of the cap first...the bottom of the hole and only a little of the side is where contact needs to be made...use a boot like the coils used in the 60's and 70's to hold the wire down in the hole.
Use a conventional Autolite #275 spark plug and time with a normal timing light.
To see the timing mark location, scroll down the tuneup section from the manuals to Figure C-10 on this page:

Timimg spec is listed as 5 degrees before TDC.
Make sure your points are properly gapped OR use a dwell/tach for, in my opinion, an easier and more precise setting. The instructions are on that same page linked above.
If the fuel filter wont fill up with fuel, you may have a restriction in the fuel system. Sometimes there is crud in the tank that needs cleaned out or in the lines. There is also a "sock" type prefilter in the tank that is known to deteriorate with modern gas and can plug the line. In such cases, members have taken off the fuel line and blown compressed air back down the line into the tank to blow the "sock" off the line and stop that restriction. You could also have a weak fuel pump.
Can you verify that the pump is pushing fuel to the motor?
Do you have an electric fuel pump you could put in the line to see if it pumps fuel when the stock one doesnt?
