Score! Great wagon. Yes, it's an iron 225—a 1963 engine, by the stampings, so likely the car's original motor. Those chrome V-wingnut things are an aftermarket accessory to distort the valve cover so it no longer seals well.
Tune-up parts and technique suggestions are in
this post. Carburetor operation and repair manuals and links to training movies and carb repair/modification threads are posted
here for free download. Might want to do the
fuel line mod and the
HEI upgrade. More generally, take a look at
this thread.
