Pulled the carb apart again tonight. This time I gave it a thorough inspection. It can truly say I have no idea how this carb works. I assume the vacuum from the motor pulls the fuel up from the tank, but I can see no check valves or balls to to keep the fuel from draining back down the lines. It seems like a long pull to draw that much fuel with a single pull of the rope. After a dozen pulls the plugs are still bone dry. I’ve given up for the night. I found the jets are only open about a quarter turn from seated. Tomorrow I’ll try opening up the jets and see if things change. Here are some photos. Note that the fuel pick up and jets are located in the tank and not on the carb.
