Sorry I didn't mention that my concern is with longevity in a can. I have no problem running the fuel in my truck because new is pumped in on a weekly basis. What I do have a problem with is pumping into a 5 gallon can for small engines & it souring up within 3 months. Even my new John Deere lawn tractor manual warns if you have ethanol gas that's more than 30 days old, don't use it. That tells me a story right there. I use the good stabilizer sold at Tractor Supply but have my doubts that keeps it good for more than 5 months or so. Amazing what Washington & the "greens" throw at us without giving a crap if we want it.
Mr. Shelby, you rebuild carburetors. I'd like to hear your opinion. What kind of messes have you seen on these 2-cylinder carbs using 10%?
