After Market Carb

Me, I'll defer to you on that point. I believe you, but I was always able to make the traditional-type carbs (Carter BBS/BBD, Holley 1920/1945, Bendix-Stromberg WA3/WW3) work well and I sorta see the Webers as a black art I'm not really interested in learning (that may change once it becomes completely impossible to get a good factory-type carb any more). I understand the Webers are very highly tunable, but that also implies having to do a lot of tuning (spend a lot of time fiddlefutzing). One thing that puts me off them from the practical standpoint is air cleaner unavailability: those dumb little rectangular K&N "filters" do an okeh job of keeping spiders and rocks out the engine, but as far as actual dust and dirt, they're lousy (see here and here—"After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms. Compared to the AC, the K&N plugged up nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt").

I'll admit that tuning them is a bit challenging, I'm still learning how to tune mine. I also didn't grow up tuning traditional carburetors like Carters and Holleys, so the Weber is what I've learned the most about.

As far as air cleaner support goes, that just became a lot better. Webber came out with a universal air cleaner adapter plate that allows you to use any standard 5-1/8in round base air cleaner. I bought one and put a Mustang "Cobra" oval style air cleaner on my Slant.

Part number (from Carbs Unlimited) is 99010.457 and it's a genuine Weber Redline part, costs about $27 if you shop around.
