SORTED - Spoke with the mechanic at the local dealership as we looked at the example on their shelf. Turns out the choke return sping is way stiff and you virtually can't pull against it with finger pressure on the throttle lever. Mechanic said he nearly always replaces the spring with one with less tension - also I need to hook the choke cable onto the lower of the two holes on the throttle lever to give that little extra travel.
