Yep, the Weber choke butterfly should be mostly closed (horizontal) when the engine is cold, and essentially vertical when the engine is warmed up. The choke is adjusted by taking off the air cleaner top, loosening three small screws and rotating the round choke heater element/bi-metallic spring (engine must be fully warmed up for this) until the choke butterfly is "just" fully open, then rotate the other way "a tad", and tighten the screws. Replace air cleaner top.
Is the electric choke heater wire plugged into the rear of the alternator like it should be.
