Before digging into the mag we decided today to swap out the new plugs with the old ones. We discovered that when my ercoupe cups were installed that the plugs were put in with a gasket so we had not only the cup acting as a gasket but the gasket as well taking the plug a bit far from where it should be in the cylinder. Anyway with a little bit of difficulty we were able to pry the gaskets out of the cups and reinstall the plugs.
It ran fine after that! What a relief!
