I'm not an expert on the 150 I'm afraid, so you'll have to wait until the likes of Matt or Stephen come along. However,
Oil pump should be set to max as the throttle does.
Power Valve should be set to open fully at max revs - or somewhere about 6000 (at a guess). On the 250 there is a proceedure to fool the system into thinking it needs to be at maximum when the engine is off, but I don't know if that setup applies for the 150.
As for the kickstart, I dunno! Never had one fail, so I've never had to dig into it. I suspect there's a cog sticking on a shaft though...
