Opinions on EFI system

[patrickt]

What I love about my Holley carb is that it requires constant attention, fiddling, and periodic rebuilding. Plus, it has the unique ability to just break down and spring a fuel leak when it had been untouched and sitting in my climate controlled garage for weeks bone dry. You have to love that in order to appreciate a carb. I would never put up with that crap on my other "normal" cars, but with the Cobra it's kind of like "ok, I get to yank the bowls off again, hurray."

Both of my daily cars have EFI.

The number of issues I have seen with customers EFI cars, I still prefer carburetors.

A single 4 barrel carb won't cause single cylinder misfiring or flooding like a stuck open injector. Guess what happens to the engine.

Oh, and when she's not leaking, the ethanol in the gas is eating up the cheap pot metal that Holley seems to use. Here's a pic of my metering block that kept clogging up the air bleeds with mysterious chunks of white crap. Hmmmm, wonder what that stuff is. This baby wouldn't even clean up either. The replacement metering block has been holding up much better though. And, yes, that's Ellie's white fluffy butt in the background.

Being 67 I was quite particular about wanting a carb.....particularly the Holley. I grew up working with them which also included the old carters, quadrajets and enjoy the tinkering as you say. They can be touchy devils occasionally but if you know them, you can figure it out. To me, it's part of me enjoying the car. With that being said, my wife treated me to this for Christmas. A new 870.

Well, that's a beauty. I wonder if the chunks of pot metal in the air bleeds will be dark blue instead of white. That said, I still love my Holley, I just enjoy complaining about her.

Kind of like the way we and our spouses complain about each other!

I think I see the problem Patrickt. The two main jets are clocked incorrectly!

The jet on the left has its screwdriver slot clocked at approximately 2 o'clock and the one on the right is clocked at approximately 10 o'clock. This potentially sets up a trans dimensional vortex while the engine is running that sucks the cheap plating, that Holley uses, off the metering body replacing it with some form of white inter-dimensional waste material.

Who knows for certain but possibly under full throttle an Einstein-Rosen Bridge could appear in close proximity to the mis-clocked main jet originated vortex potentially penetrating the protective bubble of another universe in close proximity to our own. If that would happen it's possible a small black hole could form swallowing the entire Holley carburetor — perhaps even the air cleaner!

Your friend in time and space,

Back before emissions and carbs were on everything I used to run a little marvel mystery oil in my gas. I wonder if an additive similar to that would help with that white build-up? Of course, when the fuel evaporated then you would have a slight film of mystery oil left over.
