Customer says this air filter housing is original. But with this air filter in it, I can't see how it could draw air. Both ends of the AF block the housing holes, so it's gotta be the wrong air filter, right? The tin end, has to go towards the holes, which blocks the housing holes.
My problem is, I can't find an AF that fit this housing.
The housing is about 2 1/4 deep (to the curve)
Here's what I got. BTW, Partstree and the others don't seem to have anything close to this. Could the housing and the filter be wrong? Or just the AF.

What you need is the tapered filter. I believe it is PN
Tecumseh 30727
or
You need to order the complete air cleaner assembly PN 730127 or the foam filter 31700

Thanks man. This is one of those situation where I knew I was right. But was hoping like the dickens I was just missing something simple. None the less, customer was gonna have to wait a few more days anywho, because the muffler I got from Stens didn't come with a gasket.
So I'm ordering all this from partstree. A little more than Amazon. But can get it in 3 days, instead of Amazons 4 or 5.

Thanks again.
