    Thanks for the tips, guys!

    Although, I’ll try again tomorrow, I did try to move the crankshaft fore to aft, and didn’t notice any play. Maybe the previous owner didn’t have the flywheel torqued down to spec?

    The o-ring in the carbon seal was a little brittle, so hopefully replacing it solves the issue (fingers crossed). Could someone confirm that the part number for that o-ring is 302540?

    Got all of the oil and dried up old grease off the armature plate tonight and dug up a good coil to replace the dead one. Going to give the condensers a test, too. Hopefully when I get the new o-ring and get everything back together I’ll be able to report that it starts in two pulls like Dave’s!
