Hot Rods Ethanol Shield?

I have some sta-bil I bought last year , for my camping generator. Ill check the label if it says "ethanol protector"

 

It would be interesting to see the inside a secondary bowel in a vacuum secondary Holley type carburetor after using 10 percent ethanol mix for a few years.
Unless it's a drag car or has a young driver rotating fresh fuel in the secondary's, it will be contaminated.

 

what, you don't get the secondaries open every time you drive? Shame on you!

 

My new power washer came with this stuff and I used it but I can get ethanol free gas here which solves the issue.

 

Jim I might be guilty

Had some fun experimenting when E-85 was $1.50 gal about 10 years ago, changed the jetting and the alcohol accelerator pump in a spare 3310 vacuum secondary Holley 750, then bolted it on the Avtar 64.
The engine is a 0 decked flat top piston 350 with about a 10 to 1 compression ratio with 64cc cast iron vortec heads.
Ran one full summer with about a 50/50 mix of 87 octane E-10 / E-85, after tuning the car ran about the same as the more expensive non-ethanol 91.
End of summer changed back to run non-ethanol 91 in a couple of tanks before winter storage, inspecting the fuel bowls both primary and secondary jets looked like they were sandblasted bowls lost some of the plating inside with secondary parts worse.
Didn't mess with it again as the ethanol prices increased and it wasn't worth the trouble

Note: The pressure regulator in the 2-year-old mechanical fuel pump failed the next summer

 

Ask and you shall recieve

 

Ethanol was for sure ****ing up the leather accelerator pumps in the 1 barrel Carters I was running on my slant 6. After switching to ethanol free fuel the third or fourth time I rebuilt the same carb, the accelerator pump lasted until I replaced the carb with a modern ethanol-safe carb. I would only be worried about ethanol at this stage if I was going to leave the car to sit for months... which I am not 'cause I drive my old **** rain or shine.

I currently run ethanol gas in my Model A without any worries, but may switch when I replace the simple updraft carb with these Chevy 235 carbs... the accelerator pumps in those are made of rubber that I am not sure is eth-friendly.

 

Actually that picture is misleading. That came from sitting for about 4 months

 

Looks like running moth balls to raise the octane

 

Ain't that crazy looking? It was mushy. I had my front bowl off yesterday and it was clean. I figured it'd be nasty.

 

How about a picture of inside the rear bowl for Jim post #33

 

The Stabil product with the ethanol coverage is called Stabil 360. I bought it for Little Truckdoctor’s 110 Polaris, but now I use it in everything. So far, so good (fingers crossed).

 

Up here it's best to run small engines out of fuel before winter storage. M/C same deal, supply valve off, run till empty, and Sea-Foam in the tank. My pal does small eng. repairs and 85 % of his work is fuel left over winter. Even long periods of inactivity in summer will begin formation of "crusties".
