Don Tanner After you make sure your condenser is grounded good you can remove the plug, lay it on top of the engine with plug wire connected.With points open turn key on and short asross points with screwdriver and the plug will fire. If you have weak spark there, remove wire from plug, put plug wire about 1/8 inch from ground and do it again and see if spark is hotter. This would eliminate the plug and plug wire.Your problem sounds like the points aren't grounding good when closed. Just my 02c
