Thanks again for the help, but I didn't find the answer.
I found the right coil, and replaced the old one. It still will not fire. I removed the flywheel and checked the key - no problem. If the coil is good and the flywheel is properly aligned, it seems to defy the laws of science that there is no fire. The magnet on the flywheel seems a little weak. Maybe I'm stretching, but is it possible that the magnet loses its magnetic power?
Thanks,
