Yesterday, I finally ran out of gas, 430 miles from last fill-up. Dumped in five gallons that I had with me and motored two miles to the gas station and filled up. In total, 38 gallons.
I had some SeaFoam with me, enough for 44 gallons, so I dumped that in during fuel fill. I had read the info on all the SeaFoam type products at the parts store. Most didn't say much at all. SeaFoam had the most info, but they all seemed about the same. The most consistent was to use one once per one gallon. You can use more if you think the 'gum' build-up is sever.
Today I disconnected the battery for 30 minutes, or more.
Now it's a matter of time before I can see any results.

Sorry, I have to say this: gasoline is a strong solvent. If you wanted to clean almost any type of gunk, and weren't afraid of catching on fire, you could use gasoline. Adding another solvent into your gas, in very low concentration (one bottle in 35 gallons), is unlikely to do anything. It's like adding a shot of simple green to a bottle of Dawn dish soap. You just have more soap.

Well, after I filled the tank, the digital read-out said, "410 miles until empty". After the battery disconnect it says, "560 miles until empty". Considering that I just got 430 miles on a full tank, the 410 estimate was acceptable. Hopefully it will sort itself out soon.
Yes, I have used gasoline as a solvent, works great. Old gas turns gummy and fresh gas usually doesn't remove the gum and turpentine or shellac like residue. I've worked on enough old cars in my time... been there done that... That's why SeaFoam or some other snake oil is necessary. I did not use one small can, I used two large cans. One once per gallon, I used enough for 44 gallons in a 38 gallon tank.
It's still a waiting game to see what the long term results be.

The results are in!
I've burned up some gas and watched the needle and trip-meter.

Which was more effective, the snake oil or the battery disconnect?
I didn't want to spend the time doing a scientific experiment, so I did both at the same time. My best guess is that the battery disconnect (with tank full) was more effective than the snake oil.
Thanks for your advice everybody.

- At 100 miles the needle was on the 3/4 mark.
- At 200 miles the needle was on the 1/2 mark.
- At 300 miles the needle was on the 1/4 mark.
- At 300 miles the digital readout thinks I've got fuel for another 200 miles.
