I appreciate the input. Unfortunately in this part of Texas, you get E-10 no matter what pump you go to. Premium gas? E-10. Generic stuff? E-10. I normally use Sta-bil, which normally does the job without issue with regards to fuel storage for about 3-4 months (I try to rotate gas out well under the six month mark.)
I have not had that good luck with Seafoam. I added it as per instructions, and my generator would stall with white smoke, like it was electing the next Pope, when even the lightest electrical load was applied, so I let it just run dry (took almost 20 hours.) Second time, about a year later, same issue, any load, the generator would stall. So, I pumped the gas out.
Techron seems to be for injectors. Would it be useful for carbs?
Car/truck engines are a different beast altogether. I wouldn't hesitate to SeaFoam a vehicle engine if I had issues there, but the tiny jets on a small engine are a completely different story.
