The enricher was indeed loose. What should idle speed be cold with enricher open? I am correct that the idle adjust is that little black knob near the carb, yes? Which direction for speed up/slow down? REALLY trying to avoid this possible manifold issue...I'm too broke for that!
Yes the black knob under the carb right side is the idle adjust. You don't adjust anything when the bike is cold. Get the bike to operating temp and adjust the idle to 900-950 rpm
. When you pull the enricher it will add extra fuel thru that circuit and the idle will go where it goes. There is no adjustment for cold idle except how far in/out you pull the enricher knob out. That controls fuel flow to speed idle up/down when cold.
