Ive never had some many carb issues with lawnmowers , weedwackers, log splitters..etc.. etc anything with a small carbs nothing but trouble.. I`ve started putting ethanol additives in everything.

If someone can post pictures from me I can show what E -10 and E-10 treated with 2 different stabilizers and what NON Ethanol gas looks like after 1.5 years stored in glass jars. If not, no bigger I already seen the outcome.

I'd be real curious to see the photos but can't post either... maybe you can PM them?

I have had fuel lines on snowmobile, older chainsaw, and 2 older outboards disintegrate in the past few years.
Granted they were older stuff, but were fine for years until the ethanol blends came around.
E10 is one thing.
Now our government wants E85.
That is going to be a A LOT more in the mix and make A LOT more issues for stuff not equipped to handle it.

I got me a 1952 ford 8N to cut the grass and she has been livin on ethanol for the past 4 years with no problems. My old outboards, 98's haven't even had a plug change in three years. i did change all the fuel lines three years ago and will probably do it again this winter if we have one.

yeah and a blind squirrel gets a nut now and then eventually it will catch up with ya though.

How old Is you holley ? I have a Proform which is base of 4150 holley been running over 10 year with that carb with E10 Ethanol fuel have never had a problem. If you let your boat set not matter E10 fuel or fuel with no ethanol you will have problem with any carb not just holley.
