carb newb

[canonball]

Hey guys, I'm doing my first carb rebuild, going pretty good so far although I'm getting into the tricky part of getting it put back together (correctly) and then the tuning which will be fun I'm sure. Anyway, before I start getting it back together I wanted to post a couple photos so some more experienced individuals could look it over. Mainly what I noticed is in the main body, in each of the barrels, there's a layer of crud that's got a rough texture and super tough to get off, not to mention it's tough to even get in there with a brush. The photos are from before the carb dip but that part looks about the same after I pulled everything out of the dip after letting them soak overnight. I should get all that gunk cleaned off before reassembly right? Probably a dumb question but just want to make sure. I also threw in a photo of the throttle body, just because.

no idea when it was cleaned or rebuilt last
