The fuel pump is definitely good. I checked this by shutting the fuel off at the tank and it was strong enough to colapse the primer bulb when I started it so I don't think it is a pump issue.
The coil is brand new. I put a fresh coil, cap, rotor, set of points, condensor, and plugs in her.
I installed the water separator after the lines had been primed with the bad fuel. There is a fuel filter that is also in line to the carb and it is not stopped up. The separator began to collect water as soon as I installed it. It was late in the day and the alt belt snapped (I was planning on replacing it anyway) so I was forced to quit but I will continue this weekend.
For the trip home, however, I am going to run on fresh, clean external tanks. I am fairly confident that the stumbling I was experiencing was a result of the risidual water in the lines. I've had water in fuel before on other primitive carb'd engines and I had the same symptoms. It'll run perfectly and then start to stumble and either stall or you can coax it through these spots with a combo of the choke and throttle to try to pull more "fuel" through.
Unfortunately I only got to run it a little bit because it kept pumping my entire bucket of coolant out within just a few minutes of running.
Before she goes in the water I am going to confirm that she's happy with the externals. If it can run for a while without issue on the external then I think I'll be good to go.
When I get her home I am going to open the top of the tank and inspect it. If it is as bad as some of the aluminum tanks I have seen, I will look into a replacement unit.
Thanks for all of the valuable input.
