I agree.. and I did buy one.
I knew that, my post was more to explain to those that did not know, why they work better, and what the issues are for th eold way of dong things.

I suggest removing the spark plugs and putting a teaspoon or less of Mixed gas directly into each cylinder. If it starts and runs a bit, you need to look at fuel. If it still coughs and spits, look at ignition.

You have spark and compression. All you need is fuel. Try what Charlie (Olcah) suggested and see what happens.

Well, the timing tool will make your timing more exact for sure. But, in your case, setting the points to .020″ on the high point of the cam will surely get it running. So, I think you have some other issue going on here.  Are you sure you have the coils connected to the proper plugs? Are you sure you have the coil primary leads connected to the proper point set?
To me, it just sounds like the ignition is 180 degrees off, could be as simple as the plug leads being backwards. When the plug leads are backwards, the engine will only cough/spit/backfire, it will never run.

Here is something you might check. Mark the center of the magnet on the flywheel so you can see it. Rotate the motor till one set of points start to open. The coil that your mark is at should be wired to the set of points that just opened.  If not, at some point, you got the coil wires to the points switched.

Doesn’t the picture show the coil’s green wires going to the proper points …under the coil passing by the condensers and attached to the points & condenser wire ?
Condensers are new but maybe they test bad.
No results yet on the front coil being wired to the top plug.        Metallic strand wire used ?
what is the measured OHMS value from plug boots to engine frame ?
I have no diagram of parts on the QD13 but it is possible the carb is a bit strange compared to later year models
suggest you read up on early QD-FD carbs in the johnson service manual section..  page 117 and up a few
