Let’s get away from the jiggle for now, an A will run with or without the jiggle. You say you have spark ! at one cylinder or all 4 ? It would be nice to know if all 4 are sparking.

Check to see if your timing is correct, with all of the spark plugs out, connect the #1 on the distributor to a spark plug laying on a head nut ( you can use a jumper wire ) , with the hand timing lever up turn on the key switch and crank the engine over by hand watch for spark at the grounded plug.

If you have a good spark ? remove the timing pin and invert it back in the hole, with your thumb on it pushing in hand crank the engine while looking for spark at the grounded plug, you should feel the timing pin move in slightly and see the spark at the same time. This will verify that the timing is correct.

Now that you know the timing is correct and you have spark at all 4 cylinders, put everything back in its place . With a fully charged battery let’s see if it will start, turn the GAV open 3/4 to 1 turn open , gas valve open , hand timing lever up , throttle lever down about halfway, key switch on , pull out the choke and hold , hit the starter cranking 2-3 times and release the choke, it should fire up now.

If it doesn’t fire up repeat one more time pulling the choke out for 2-3 , it should be running. If it doesn’t start up, get out and see if you have fuel dripping out of the carburetor. In the Ford operation/ instruction manual after turning your engine over 7 times you should have fuel dripping out of the carburetor. If no fuel dripping you have issues with the fuel system.
