This. 100x this.Find a gas station that has alcohol-free gas (most QT and newer Murphy stations have it now), fill it up with that and add the StaBil. I had a 6 year-old Honda Rancher w/less than 30 hours on it, and I ran that fuel religiously w/o ever a problem. That's all I run in my small engines, and I have ZERO carb problems. It's that damn alcohol blend that causes the problem.
If push comes to shove, drop me a line - if we don't have one of our long-standing trustworthy members close to you, I have a man I TRUST up there that would do it for you if asked.
I think 2 reasonsfor some reason small engines especially two-strokes seem more affected by the ethanol blebs of gasoline.
I think 2 reasons
the fuel tanks are vented more and allow more pressure equalization, therefore more air/moisture
And they still have carburetors..needle valves and really small orifices that get gummed up easily
The process that happens is called phase separationThey let that ethanol sit in the small ports and solidify (or whatever it does to plug them up).
Yep. All modern vehicles have a semi-closed gas tank and suck the vapors into your intake to reduce pollution. If you take an empty, closed can and put a small hole in it and leave it outside for a while, water will collect in it. As it gets cooler, it will suck in air and water vapor. When it gets hotter, it will push out the air, but not all the water vapor. Eventually, the water vapor will condense - I suspect the same of small engine tanks.the fuel tanks are vented more and allow more pressure equalization, therefore more air/moisture
The 10% ethenol doesn't do well when left in small engines from my experience. If I let my generators set more than a few weeks they are difficult to start. This may be due to the higher humidity than in Colorado. Hasn't been a problem this year as I've needed to use the generators during several outages.Interesting observation on ethenol:
My son had a modded pontiac grand prix GTP that was converted over to run on E-85.....
Son moved away for a while, so it stayed parked in my driveway in colorado for about 2 years, with a 3/4 full tank of E-85. Never got started, Just sat for 2 years.... Drove the tank of 2 year old E85 almost empty, then refilled with fresh E85, couldn't tell a difference
I'm a lot less worried about fuel "going bad" these days.
