I've installed my Ztherapy SU's and have a question about the choke cable attachment. Yes, I've viewed most of the video (doesn't show that angle shot), read through three books on SU's (including the FSM), and searched prior posts. My thoughts are to lift the choke levers up until the levers just contact the throttle shaft and tighten the cables. This is how it was done prior but I don't know that it's correct. The other option is to leave the levers full down, cut some cable sheathing to expose more cable, and attach to the levers in the full down position. Any input? Thanks...

You need to install them using the first method you describe (lifting the choke levers up until the levers just contact the throttle shaft and tighten the cables), otherwise you will not have enough range to open the chokes fully.

Thanks, Steve.
