Thanks for your input. Yes, I noticed that the 180 degree movement back and forth seems to work best: better than cranking with the starter, though the latter method also works but seems to be less predictable. The first time I started it, just cranking the engine over seemed to steadily suck in the fuel; the second time around, it was more difficult. I'll use the 180 degree method going forward.
BTW - nice numbers. It really is a great engine. Can't understand why on earth Yamada doesn't just sell it as a CDI directly!

Hi Atul,
First run of the day open the throttle and crank the engine 180 degrees backwards and forwards to actuate the pump so that fuel is drawn to the injector pipe; you can see the fuel progressing through it. If after a while it hasn't reached there, there may be some congealed fuel slowing things down a bit in the system (especially on cold days), or if you've got a long tank feed, it might just take a while to get there. Either way pull the fuel feed from the tank to the pump, and ensure fuel can dribble out of it. That way you know you've got fuel to the pump ok. Reattach the pipe and repeat the cranking thing with the throttle wide open. Needless to say, only do this if you are certain the ignition unit is off with the CDi. If you still can't see fuel moving to the injector then you've either got a blockage or the needle is shut.

Hope this helps
