Okay, so I made a dent in the pipe to make it fit... If I had the proper tools, I'd route the exhaust from that point a bit differently. But anyways, that can be done later.

I've now got it running, somewhat. Idle Jet is 42, fuel screw is 2 turns out, main jet is 170, Blue needle from JD Jet kit and clip on 3rd grove from top.

Runs well on higher throttles, but the low throttle area is a bit gunky. Now it idles crazy high when warmed up, and sometimes falls down to normal idle speeds. It seems like an air leak to me, but it could due to the idle jet being too small, i.e. getting too little fuel?
