Thanks Max,
I ended up getting it running by just turning it over with the drill and adjusting the carbs at the same time and it started firing and ran for a solid 15 minutes or so.
I'm now having trouble adjusting the carbs properly. If I adjust as per the instructions it doesn't seem to run, yet I am struggling to get it to idle nicely and then pickup with throttle. I can get it to idle quite well, but nothing else. I'll get there....
