Quick update here: I've been going back and forth with Hitchcock's about the cable not working.
After seeing their photos of their own carb and it's setup, I had a hunch they sent me the wrong carb. After measuring it they in fact had sent me a mikuni VM36, not VM32.
Hitchcock's has been great, they apologized for it, apparently all of their carbs come to them prepackaged and this VM36 must of gotten into the mix from the supplier by accident. They're sending out a new VM32, I'll get it mounted and hopefully the cable will have plenty of play to adjust!
I've got some parts from this swap that I'd like to offer up to members here, think I should start a new thread or post it here?
