I was only talking about 250-275 degrees, a heat gun won't melt your carbs. I have some parallel pliers I'll loan you, if you want to try them? They have some compound leverage to a degree. Cutting a slot for a flat blade screwdriver is pretty good advice. A fine toothed hacksaw blade would get it done. But you have to get the carbs in a vice or something, because sawing on a jiggly piece will just make a mess of it. Tie them down to a board if you have to.
