Use Seafoam

[Al.Fisherman]

Most fuels sold today contain up to 10% ethanol (at least around here), which pretty much eliminates the need for "dry gas" - which is just ethanol or methanol. The alcohol will attract and hold water in suspension until burned. Problem is that in a vented fuel system, the ethanol can draw moisture from the air, and may attract so much over time that the ethanol and water will separate from the gasoline. This leaves the gas/oil mixture on top, and the ethanol/water mixture at the bottom of the tank. (ouch)

Which will now gather in the bottom of the carb bowl. As the bowl rusts from the moisture the fuel filter is of no use. In fact you will introduce or can introduce more containments into the carb then you would using 100% gas and no filter.
E-10 is a major issue with boats, it is so bad that sometimes the fuel separators (looks like a oil filter) we use can't keep up with the moisture problem. Another issue is that E-10 will and can eat up cheap fuel line hose (wonder what the Chinese use). One of the first things I did was to change my fuel line hose to a known not effected hose.

that's also what I have been thinking
but
yesterday after noon I was at an auto parts store -- Kragan
the guy working there says that he pours a whole bottle into his
big Honda motor cycle THING
and it doesn't hurt to use large amounts in anyTHING
goes against what the mountain Lady tells me
everyTHING in moderation

it's a tough THING to do at times for the Mountainman

To me, it is much like " pain killers." Let's see,,, one a day works good, so I'll bet 8 a day works even better !

Correct, besides if the manufacture recommends a 1:128 ratio, why go to those extremes. In LARGE outboard engines you don't use that much. Just a waste of money not to mention the amount of smoke it would put out.

Also remember that Sea Foam contains powerful solvents (to clean), and while the brew does contain oil, too much of it could break down or dilute the lubrication in a two stroke engine.

I pretty much stay away from additives, except for fuel stabilizer. All of my power equipment gets stored properly, so carburetor deposits are not a problem.

I kinda failing to see why I need SeaFoam in a well maintained two stroke, but whatever floats your bowl.

I am curious as to the chemistry and how it helps with hygroscopic EtOH/fuel/oil mixes. Can someone explain this in detail? I have some guesses, but does SeaFoam say, or is there a technical link?

Most boats on the water today run with 2 cycle engines. There is a major and I say major problem with E-10 and 2 cycles. E-10 will rust your tank out...maybe not today but the time will come. Here is a link

Yep, the 10% " crapahol " gas can be blamed on many engine problems, 2 && 4 stroke. I have seen these problems in everything from weedeaters, to boat motors, to larger trucks. I am to get a lawnmower this week & from the owner's description of the problem, I KNOW it is water in the fuel system.
I made this post a little while back that is worthy of reading to everyone .

Oh, I have NO doubt ethanol in gasoline can and does cause problems. How does Seafoam help?

From their site...
As a fuel system additive, Sea Foam will clean fuel injectors, clean carbon, gum and varnish deposits, add lubricity to fuel, stabilize fuel for 2 years and control moisture.
There are other brands that will give the same results. Some will work more on the water problem, but in the small tanks we use SeaFoam accomplishes the job at a fair price. Advance Auto has it for $10.00 and the 16 oz can will treat at least 16 gals if used as recommended. 16 gals X 100 MPG equates to 1,600 miles. How long does it take for you to travel 1,000 or more? Cheap insurance I'd say.

Maybe you only need to worry about steel tanks. Most Japanese 2-strokes used plastic tanks. I am concerned about rubber parts in the carb, like diaphrams and o-rings, though. Can Seafoam protect them?
