A little update. I got the wagon running.
The motor was stuck but not terribly. I pulled the spark plugs and soaked the cylinders for a few days. First before I started spinning it, I unhooked the fuel line from the fuel pump. You don't want bad gas from the tank in the carb. With the spark plugs still out I got it spinning over easily with the starter.
The mice had gnawed a few wires on the distributor and the ballast resistor. I pulled the old distributor out. While it was out I pulled the oil pump drive shaft and primed the oil pump with a shaft I made out of a piece of 5/16 allen wrench.
Next I put in a new distributor, control module and ballast resistor. Fixed the wiring issues. Put in new spark plugs, and spark plug wires.
Last we blew out the line from the pump up to the carb. I hooked a boat motor can with a primer bulb to the fuel pump. I primed it a few times, poured a little gas in the carb and it fired up. I will try to post a link to a YouTube video of it running.
