Pics of the setup - I'm missing a vent hose or two on the carb:




This is a 1min video of it being kicked over. It fires right up with me blipping the gas as I kick. I'm bumping the throttle throughout to keep it going but it does finally idle at the end. As you'll see, it dies right away when activating the choke. Also, you can hear it stumble and sound like it's hitting a rev limiter when I throttle up.

This next one is just under 2mins. It idles fine throughout and I give a little commentary at the end with what I've been finding. I run up through the throttle positions very slowly and you can hear the bumping/stumbling it's doing. Not sure if maybe that little filter in the gas line is a problem as well?
Very curious as to thoughts and recommendations as to what I need to or should do to get this thing on track. Sounds like the first thing is an air box...?
Thanks for any help and guidance~
