Clark AU1393:
What engine is it?

I have no idea what model this is.
Trying to give my new (to me) forklift a tuneup. I put new plugs in it but I don't know what cap and rotor it needs. I am assuming it's a continental engine 4 cylinder flat head. I'm trying to figure out the right firing order. It originally was set up as 1243 which did run but wouldn't get full RPMs and was running pretty rough. On the top of the head it has a firing order of 1342 but was way worse that way. The engine code has 5967 which each digit was crossed out and another number stamped next to it, 0368. The cap has a big crack in it which probably doesn't help and the plug wires are junk. But each cylinder is firing and definitely noticeable when you ground out each plug.
It has the forward and reverse and fork controls on the steering column, if that helps any.
Does anyone know what engine this is?
Thanks!
