Fuel draw was the real concern and since it ran on "the bench" a year ago and not in the the plane, either the setup or carb was the problem. Confirming everthing was setup OK, I took apart the carb and the "dimples" in the diaphragm suggested it needed replacement. It drew fuel better after this, but still didn't run.
Next I soldered a piece of real thin brass over the hole in the choke plate. Now, when the choke is set, there is zero air going thru and it draws real well. With full choke, I flip it about 10X to draw fuel, turn on ign, flip once or 2X, it fires and studders, I slowly open the choke and advance throttle. It runs great! And finally, it starts when I want it to. A minor mod but it worked for me.
Hope this helps others.
