OK it was the old 3rd bolt completely covered by the fuel tap lever when in the open position trick.
Still couldn't get it right off due to the mower handle being in the way but enough to see the choke and it is not even working. When I push the lever into the choke position the throttle linkage is supposed to pick up the choke linkage and take it with it but it is too short to reach swings right past it and I'm blowed if I can see any way to close the gap - the engagement tab needs to be longer by about 2mm - it's as though there is something missing but the manual doesn't show it.

If I hold the choke against the stop with a screw driver it starts first kick from dead cold - like it should. Email sent to Honda
