Well the kit came but without the O ring I wanted, renewed gaskets and diaphrams, primer bulb etc. Now no fuel coming from tank to carby, the way I see it the small fuel line that goes from the primer to the carb must create a vacuum which should then draw fuel from the tank to the carb and then the overflow of fuel then comes up to the bulb and then overflows back to the tank via the larger fuel line. This is my assumption but probably wrong. I have pulled the carb and the primer apart several times to have a look but at this stage I don't know what I am looking at. Removed the fuel screen just to eliminate that, it has the new needle and seat with new spring. Why Tanaka had to go with I remote primer I have no idea.
