Will do on the hub pic, thanks!
Regarding the drill start, it was an easy fix. Switched from low to hi rpm on the drill and cranked the drill's clutch a couple of clicks south of full-on drill mode. Fired up, started pulling gas through the carb and ran her for about 10 minutes. Then shit started popping off and vibrating loose all over the place. I think that the drill in low revs was holding the engine back. No issues when I ran it faster.
She runs again. Thanks for all the knowledge. I feel like a total idiot for not realizing how the drive train actually was supposed to be working. Glad smarter folks chimed in.
