ID My Missing vacuum line
In the last picture there is a braided vacuum line next to the rubber ones and just above the "Y" vacuum lines, can anyone tell me where this line goes to or comes from? I finally had some time to check stuff out (crappy idle and idling very rich with no response from air fuel mix adjustment. Found the "Y" pulled off and the braided line missing (or maybe fallen down somewhere I can't see). There is a braided line over by the oil filler tube that goes down behind the engine.

Thats the one, thanks, all vacuum lines hooked up. Now any clue on where to start with the air fuel adj screw. I had hooked up a CO meter and was having all kinds of trouble trying to get my CO from 12.2 and could only get it to 13.3 (I think 14.2 is the target) so I ended up backing out the 3mm allen wrench screw about 9 turns to get it to 13.3 Now that the vacuum leaks are taken care of I'm looking for a "starting point" for the adj screw as I know its way to far out now (lean). Thanks for the great pics as I couldn't see crap back there even with a mirror, they were a tremendous help.
