Just because you have fire on the stand does NOT mean you'll have fire 3 miles from shore. As Frank noted, check that coil. Those old Bendix Scintilla coils are noted for cracking with age. You could very easily have spark now with a cracked coil, but as it warm up, gets exposed to humidity, etc., that spark will weaken. The points are no longer available, though, so be VERY careful with them.
