The backfire is a lean condition. turn that long brass screw out. they are very touchy on the settings. The air silencer cover makes a difference on how it runs too. FWI you can just hook an external tank up to the fuel pump without having to buy the connectors, just a fuel hose and primer bulb. Let it run and warm up. that water pump did not look the best, it had some memory and should be changed. The controls have the key switch. Im assuming that was part of the cut pigtail you showed at the beginning of the video. You are going to have to buy the control box and stuff or find some parts motors and convert it to a tiller and she will sell pretty fast. That block is 100% in good condition with plenty of compression.
