Strange Secondary Air Valve

(1/2) > >>

Novarolla05:
Hello all,

I came across an air valve setup I've never seen before, and can't seem to find anything about. The carb number is 17080212. One of the air valves has a small flap attached to the underside at about a 45* angle. The other flap is normal with no notches or anything. Since its only on one flap, I'm thinking this carb has been reworked (incorrectly?) at some point, but its only for parts so it really doesn't matter (primaries look melted from a fire or something). Has anybody else seen air valves like this before, and are they any better than just a plain air valve?

I'll try to post pics when I get home if none of this makes sense.

Thanks,
Richie

 Can you post a photo of what you are describing?

Novarolla05:
Ok, I finally got around to snapping a pic of the air valve. Here it is:

 I have never seen anything like that. Looks like some sort of "baffle" maybe? I don't know. We will see if someone recognizes it.

Novarolla05:
FWIW, the part number stamped on it is 58583. The other air valve that was on the carb (the normal one) was 58411.
