As to engine not starting when you choke it. I have had this happen when I removed the choke assembly. The problem was the shaft holes in the carb allowed air to enter, even though I had my thumb over the intake. Solution, plug up the shaft holes. If this is not the case and you still have the choke assembly, there may be a hole in the choke butterfly that needs to be soldered closed. Good luck, red
There is no choke that I can see. I'll take off that brass pipe he has attached to the carb, I honestly don't know why it's there, and give it a try.
