Yes, I have a 12 v flywheel. Also, the engine doesn't have any tight spots at all. Compression is an even 110-120. Every connection is beyond tight and bright, less that 1/2 a volt drop on both positive and ground circuits - the cables are new, the battery is new.... I was really [censored] that I wasn't able to troubleshoot this. Well, until this little gremlin.

So, is there a different tooth angle or geometry within the 168 tooth, 12V flywheels? Or, if I get a 168 tooth wheel am I all good?
