Just getting to the valve adjust on the 914-6, found that
#4 and #6 output ports look different. #5 + all the right side,
are just carbon like from idling rich. What does #4 and #6
look like to you? Thanks for any help.

Mike's got a good thought. If the shafts are leaking air (as mine do, also) the idle doesn't want to settle down much.

It's pretty tough to set the idle mix if the idle isn't steady. Did you try squirting some carb cleaner around the shaft ends?

Just out of curiousity, do you still have the stock venturis in the carb? Mine had been changed to a larger size a long time ago and I recently swapped them back. It's interesting the change that it's made to the engine at idle. It doesn't make logical sense but the engine seems to be better behaved even at idle.
