Default What is this thing? (intake related)

I have noticed some little black specs all over my carb and intake manifold. While taking the breather off I noticed this screen thing with a trillion of them in it... with a hole. It sits just inside the air filter. I took it off (was glued down). What is it? I'm guessing maybe it's another part of the smog system? Do I need it? The air filter fits fine without it.

Carefully hang it on the wall (of the Smithsonian).

But... But... It was inside the actual air filter. Like the air filter was surrounding it.

Yep, it's a flame arrestor and I can't imagine why they used them for just a few short years.

That, my son, is an **** ring. They are known to fall out of your behind after you realize how much mony that car is costing you. You only have 7 to begin with so be very careful!
I'll show myself out now!

Here's a photo of it. It's the inner ring inside the air filter.

Thanks a lot for posting that tehjrow

You just solved a mystery for me. I had always wondered why there was some blue adhesive/sealant residue in my dual snorkel air cleaner box inside the circle of the air filter on my '81. Now I know.

I guess I must have had one of these devices in my car once upon a time too. Whatever it was is long gone, but I can only assume that they came from the factory this way.

Mine had a hole in it and a million little black specs came out and went into the carb. I'm sure that's really good for my car.

I'm going to guess a charcoal activated filter of some sort. Probably to absorb fumes from carb and evaporator system.

I believe its filled with some type of flame retardant. Kept a backfire through the carb from getting out of hand; Flame Arrestor. More common on boat engines for obvious reasons.

It's a flame arrestor. Generally layers of metal mesh.
