Interesting... I didn't know there was a difference in two stroke oil
between air & water cooled motors. Which is designed to run hotter... The
Air cooled stuff? What symptoms will using water cooled oil in an air
cooled motor have? I think its likely i used some old redline two stroke
oil I had laying around from my GP motorcycle (2 stroke) days...

The fuel pump is in the carb or separate?

Yeah, it'll idle fine usually (both on and off the choke), until you give
it even a tiny bit of throttle (like, anything at all, well below the rpm
the clutch kicks in at so there's no load), then it dies.

Ok, that gives me some stuff to try. Thanks!
