Hi Guys, most greatly appreciated quickie steer on a Yamaha 4 stroke fault. Plenty of spark but no ignition and plug totally dry, replaced petcock in tank, replaced carb, (even removed carb and sprayed easy start direct into manifold while cranking), plug still dry with no ignition ? I had removed the plug and filled the plug socket (in the head with tissue, turned the engine and it blasted out), hoping to indicate compression ? I'm at a complete loss as to what to look for next, any ideas would be most greatly appreciated Thank you very much
