Your problem may be the wiring. Or air gap. Remove the push on connector from the coil. Is there spark?. If not, Try different plugs or a plug that you can see a

good spark from a different small engine. Next loosen the coil screws with the flywheel magnets away from coil. Put 2 thicknesses regular papper into air gap, turn fly wheel so magnets pull coil down , tighten screws, remove paper. Should be spark.  need more help? email me at:  doogy@doogy1.com
