I ran seafoam in my 2 cycle mix for 2 chainsaws.Both saws lost compression and had to be rebuilt. I don't use it anymore.

SeaFoam is a fuel treatment and does a good job of cleaning fuel systems but it's not a stabilizer, people get them confused. For long term storage I use stabil marine fuel stabilizer in my boat, and it only gets ethanol free fuel.
For small two cycle engines I've gone to the pre-mixed stuff. I usually get it at wal-mart but you can get it from any small engine dealer, it's ethanol free pre-mixed with good synthetic two stroke. It's about $5 a quart at wal-mart and comes in a metal can that seals well. Unless you're running a chainsaw or weedeater professionally that'll last most users months and it's far better than mixing your own in plastic cans that aren't ever air tight.

I've joined the 90 octane, non ethanol, with stabil added when purchased gang.
My 4-stroke small engines include 2 atvs, lawn tractor, push mower, snowblower, 1850W portable generator, 2000W portable generator and a 13.5KW standby generator. Picked up a bunch of 5 gal gas cans (that I numbered!), and use them in order filled in whatever internal combustion beast needs it. The gas doesn't get too old.
The smallest generator and push mower are older, and used to use any old regular gas in them, so those got a couple tanks of premium with Seafoam to clean them out when I went to ethanol-free.
2-strokes are a couple of trimmers and two stihl chainsaws. Trimmers get the premix 50-1 fuel or my chainsaw fuel. Chainsaws get good gas with stihl oil. No stabil, but might add it to the regimen.
And so far everything starts and runs when needed. STIHL ultra HP 2-stroke oil has stabilizer in it. A 100:1 mix of the STIHL ultra HP 2-stroke is a very good generator preservative. Use the ethanol free gas and normal dose of St-Bil. The 2-stroke oil gives a fogging effect.

Ethanol free and stabil here
Boat that gets used 3 months a year
Atv that gets used regularly
Jet ski that gets used 8-10 times/year
Chainsaw, weed eater, leaf blower that get used 1-2x year
Haven’t had a carb problem since I quit ethanol and some of the gas has been sitting in the barn for years

I use non-ethanol fuel, plus this: https://gumout.com/mstu/multi-system-tune-ups/It’s basically like SeaFoam, but also has PEA (Techron) in it, so helps clean up anything I may put it in that is furl injected (high pressure deposits). Usually costs the same or less than SeaFoam, so it’s like getting the PEA (Techron) benefits for free...
