SoCalPal.......you do know points gap NEVER stay the same as when you set them NEW, don't you??? Your description has all the earmarks of needing to re-gap yer points.
Unfortunately, we're NOT MIND READERS, so we need to know whether yer 8N has the weird 4-nipple frontmount ...or... the more common looking 5-nipple sidemount. Surprizingly enuff, points and condenser don't care whether original 6-volt positive (+) ground ...or... 12-volt negative (-) ground.
Iff'n yer 8N has the weird 4-nipple dizzy, ittza 2-bolt, 15-min job to remove the dizzy and adjust the points (0.015") on the kitchen table. Just un-snapple the capple and remove 2-bolts and walk. Installation is a reversal of the removal ...except... finger start the 2-bolts and then install the rotor. Now rotate the rotor until the OFFSET drive tang fits the OFFSET camshaft slot. Since the dizzy is OFFSET scheme, you can NOT install outta time. Now tighten the 2-bolts and re-snapple the capple. Simple, eh?
Remember to "polish" yer points (0.015") after installation/adjustment. Me? I clamp a clean $1-bill between the points and pull. Iff'n yer really cheap, tear a strip from HEAVY brown paper grocery sack and use that.
Many neubie shadetree mechanics, miss-install the #3&4 sparkie wires. I'd swap the 3&4 sparkie wires FIRST before I'd remove the weird 4-nipple dizzy. Why? 'cuz I'm LAZY!!! .........Dell, yer self-appointed sparkie-meister
