I just received my carburetor build kit from treatland.tv and have replaced everything but the needle seat (number 9 in the diagram).
The only problem is I'm having trouble getting the original one out. It seems like it's just a push-in sort of thing, held there by friction, so I tried to pull it out with a pair of pliers. It didn't work because there isn't much space to hold on to and all I've accomplished is chowdering up the brass a bit.
Basically I just need some tips on getting it out, I don't care about damaging it because I have a new one with my kit. (And also it's not the carburetor I'm using currently.)
