John, slow down here. You asked a question and waited a whole six minutes for an answer. Come on man. First of all, the problem with your Tecumseh is the carburetor. Order three replacement carburetos from Amazon, and try them until the engine starts and runs. Return the remaining two. I am not kidding.
As far as your torque converter questions, the one that Ole posted appears to be a standard Driver and Driven set, not the TAV set. It looks like @ole4 married the jackshaft to the new Torque converter DRIVEN using a set screw stop to a plain jack shaft, to which he mounted a chain wheel.
