I have a 4MV that I just rebuilt for my boat. It has a divorced choke. While taking the carb apart, the spring fell out of its housing. I've attached a picture of it. I set the spring with a cold engine at about the 5 o'clock position and it didn't seem to have enough spring to snap the choke back. I moved it down a bit further and the choke snaps back pretty good when cold now. After running the engine for about 15 or 20 minutes the choke isn't opening all the way.
I'm not sure I approached this the right way but I can't find a ton of info on setting this type of choke.
Thanks,
Greg
