Word Slinger at this point & time I'm not worried about fuel! I need fire right now.
..sorry..thot i read that u had fire at plug..
..the black/blue comes off the kill switch, but from looking at the schematic, if you have nothing on blak/yellow to ignition coil, but do have power in on black/blue, only other possibilities are pulser, or the diode that's in the blue/yellow wiring circuit...or faulty cdi...
..did you get a look at the schematics in the service manual?
