Here's the air filter I'm talking about. The air intake side of the square bing I've got has 4 holes, and the filter has only 2. The inside of the filter is still there, but could use a good cleaning.
I tried to do a google search to see what a square bing air filter looked like before I went all the way to the basement, because I'm lazy, and they're isn't anything about them anywhere. Since I clearly have the only remaining square bing filter on planet earth, you can have it for the low cost of helping me with some timing and wiring issues when the time comes for my rigid. It's still gonna be a while.
Also, I have the disassembled square bing itself if you're interested. It has a 52 jet, and supposedly they take different jets than regular bings, and are harder to come by. My camera died before I could snap a pic of that though...
I'll bring it all tomorrow.
