I understand the issue with ethanol gas and cars that sit a long time, but that's not just ethanol gas, it's modern gas. The fuel is engineered to atomize easier for EFI, which also means it evaporates easier. Ethanol enriched gas might evaporate/degrade slightly faster than non-ethanol, but modern non-ethanol gas degrades at about the same rate as ethanol enriched.


This is correct. The 2209 is a completely different design than the newer 2300 series Holley. http://www.oldcarmanualproject.com/manuals/Carbs/Holley/TypicalViews/pages/2209.html

I also agree about modern oxygenated gas, it is the cause of some of the headaches people blame solely on the ethanol.

The Holley 2209 and the Rochester 2G are very similar in their design and construction. You will know your way around a 2209 if you've ever messed with a 2G on a GM car. Especially a tri-power that uses three of them. Wink

I did a lot of research in college on how the formulation of gasoline has changed over the years. It is not a short explanation. Partially explaining something but not fully explaining it is how most of the (usually partially correct but mostly wrong) myths about modern gas started. It would be rude of me to derail the original purpose of this post (Holley 2209 problems) with a big essay about how vintage gas compares to modern gas. If that is a discussion we wish to have, I suggest we move it to a separate thread.

Full blown tri-power expert here and I agree.

Would really like to read your research.

I think the problem is solved. I removed the power valve cleaned it up and lubricated it and the engine is running so much better. Thanks for the info and help.

I'm not sure where you guys are getting that there are no rebuild kits available for the 2 BBL Holly.  They're readily available at Autozone.

Completely agree about ethanol gas too.  BAD juju

On top of everything else, it burns hotter, which promotes oxides of nitrogen.  They, it turn, can cause acid rain.

Yep, I have a 2GE on my Buick 231 V6. Original carburetor, actually.

My research may be discussed in a private message. I will not discuss it here in public.

That kit is for a Holley 2300, not the Holley 2209. Yet again, the 2209 is a completely different design. At no point in the thread was it mentioned the 2209 rebuild kits were unavailable, only that most are incorrect or incomplete.

By the way, if at all possible only use a genuine Holley rebuild kit on a 2300. Most of the "parts store" rebuild kits have substandard parts. Since the pump diaphragm and bowl gaskets are black, one has no way of knowing if they are alcohol resistant. At least the kit shown uses the correct style needle and seat. The "tall lock-nut" aftermarket needle and seat assemblies are garbage and will ruin the threads in your float bowls.

I got a rebuild kit from Napa for my 2209 about five years ago.
