On my cleaned and rebuilt carb ('94 Evo H-D w/ OEM CV carb), I can start the bike with the enrichener pulled all the way out but if it is pushed in, the bike dies. With the bike running, if I try to twist ANY throttle in, the bike dies. Now I'm wondering if I have the vacuum jet needle in the wrong place. My install is: diaphram, spring, plastic spring retainer (support, with the 'feet' down), and needle. The head of the needle is below the spring support so if a vacuum pulls the spring support up, it won't lift the needle I don't think. Dunno; the bike will fast idle w/ the enrichener out but any other position, or twist of the throttle, kills the engine. I'm still learning about these CV carbs, obviously. Help!
