Model A and B engines both have the same firing order , I'm not sure about the firing order of other four cylinder engines .

It's got to be either 1-2 or 2-1, try one and if that doesn't work try the other. Simples.

Most 4 cylinder engine firing order is 1,3,4,2. Old Fords are different, as said, 1,2,4,3.

I believe Ford went with the 1243 order because he though it would work better with the siamesed intake ports and manifold. 1 & 2 share a port and manifold branch, and likewise 3 & 4. This way, the fuel charge flow has to change directions only twice per crank revolution. With a 1342 (and if the porting and manifolding were unchanged) it has to change directions 4 times per crank revolution.
