My Combo, Manifold Or Ported VAC Advance, We'll See...

I believe you'll find it hard to start at 34 initial when it's hot. This is when manifold vacuum helps. There's zero vacuum advance until the engine is running so you can run say 16 or more initial and "the rest" comes in when the engine starts.
Yes, I anticipated that, and put in a separate push button for the starter. I get it crankin, and then turn the key.
