Ethanol damage/fuel stabilizer

[FredG]

Interesting. If you have a carb, you are most certainly familiar with what the inside of it will look like from exposure to ethanol.

Have to watch more closely later but I was impressed with his electric drill gas engine starter.

Yeah, exposure with unused fuel. Having had boats all my life I am familiar with ethanol fuel in carburetors but never had a problem if you constantly run fuel through them. Sitting causes problems.

You mean like this? My first primary metering block on my Holley carb was really susceptible to ethanol. Fortunately I cracked that one and replaced it with one that isn't nearly so bad. Somewhere I read that in the early 2000's Holley had a run of particularly bad metal.

I had issues with one of my carbs due to ethanol fuel. The rubber tip on one of my carb bowl float needles deteriorated and I was dumping a sh!t-load of fuel into my engine while it was running. I picked up a couple "needles", installed one and kept the other in the car for a spare. I'm not sure if Holley makes ones that are E10 resistant.

We have non ethanol fuel available so I very rarely use anything else and especially when a vehicle is in storage ...no bueno ......

I thought of this picture you posted from a while back when I was watching the video. Probably why I take my bowls off every winter and clean them.

Let me tell you, when one of those white flaky pieces you see on the metering block, that looks kind of like the fur on Ellie's butt, would lodge itself in to that tube with all the holes in it that Holley's have that head up to the air bleeds at the top of the horn, the engine would go from running beautifully to running like crap, at idle and off idle, in a matter of minutes. The first time it happened I said to myself "damn it, you wiped a lobe -- nothing else could make the car run that bad that fast. But wait, it still accelerates hard nicely... wtf??" But it could be cured just as quickly as it came, with blasts from my preferred gum cutter, Berkebile 2+2, down through the eight air bleeds. It is absolutely astounding how a small tuft of crap can make a Holley misbehave so quickly.

Can happen to any carburettor if a piece of solid debris gets in to the jetting.

I seen grass, fuel line rubber, sand etc, and well as general fines that cheap fuel filters don't stop.

A bit harder to sort on the average Holley metering block, since the emulsion tubes are harder to remove than most carbs.

Uhhhh, what about dog hair?

I wish I could find no ethanol real gas near me. I swear by stabil. If I know I'm not going to drive the car for more than a week, I fill it and add stabil. Been doing that with my motorcycles for years and never a problem.

Kojack (et al),

Here's a reference to locations with no-ethanol gasoline for the US and Canada: https://www.pure-gas.org/

Maybe there's one close enough?

Did you add them to the list?
