Hi Teebag, hope you sort this one out. No spark can be a frustrating thing when you don't know what's causing the problem, sometimes it can be starring at you in the face and it's the easiest fix. Alot of no spark issues I have had with other engines is a simple fix which involves checking the high voltage wire that connects to the spark plug, common issue is that the end of the connector that touches the spark plug disconnects from the wire that runs in the insulated black rubber insulated tube. Most of these connect by a sharp spike pushed through the rubber insulation and touches the solid copper wire inside (sometimes the spike misses the wire or needs to be re spiked to make contact). Check for connectivity from the end connector on the sparkplug side to the point on the magneto to see if it's got continuity. Also check that your coil is not shorted to ground which is what causes your engine to stop when you turn the engine off.
