We have our first start and run in the books after a night of confusion and inability to get it to run. As to why I couldn’t figure out how to get it to run, I realized that my now having a lift means my fuel bottle is just low enough not to get good fuel flow. Yeah, I’m that stupid. I went through valve timing, ignition timing, checking for air leaks, swapping coils, checking wiring, etc. for a good 4 hours before I figured it out.
The Murrays Carbs/Rae-San ignition makes the ignition part pretty damn easy. No advancer weights. Just take everything off the advancer and slide their cam over the shaft. There are LEDs to indicate timing on the Hall effect backing plate, so just set the cam at the firing mark for 1/4, loosen the 10mm nut, rotate the cam until the LED lights at the right point, tighten the nut, start it up and check advance with a light. It’s programmed in, so it should be right where you want it. Easy. Done.

There’s a bit of smoke in the vid, because I need to machine a plug for the tach gear hole. With a digital gauge, that is gone and my open hole is splashing oil onto the headers. LOL.
