Yanking hard at idle???

Got it. I took it off manifold vacuum and got it down around 18* BTDC, the Tport looked on the money granted I didn’t use a feeler gauge, and richened up the mix a little bit. It’s idling just under 800rpm, drops to 650-700ish in gear but doesn’t die, sounds low though. Soon as the rain clears I’ll take it for a test cruise!
