[Baba O'Riley]

Car is '71 Formula 400, with a just-rebuilt Rochester 7041263 and one of those “divorced choke thermostat” setups with the flat coiled spring.

I'm having problems with cold starts, it runs weak and rough at first with very heavy gas fumes. Sometimes the car only starts cold with the pedal floored – and a big bolt jammed in the choke butterfly so it’s all the way open.

Question -- the spiral spring on the choke thermostat, on a 7041263 -- does the looped end of the spring that attaches to the rod face the FRONT of the car, or the BACK? At present it's front-facing.

Just trying to make sure it's on right and eliminate this as a source of the trouble.

Thanks as always for your expertise.
