Choke driving me crazy!
While making adjustments last night. I'd bend the little rod on the choke thermostat in tiny increments at a time. Every time I'd make an adjustment, I'd pull the choke thermostat off the car and pop it in the freezer for 5 minutes so that it would reset itself then put it back on the car. I thought that would save me some time so as not to have to wait until it the spring cooled down and retracted on its own.
You got the right idea, but since the ambient down there is currently 70/80, now you just have to wait for it to warm up. I just toss in in a pail of water for a few seconds.
But here's the thing, what turns that thing off as the engine warms up?
Well, I'll tell ya,pilgrim........If you had factory log-manifolds, there would be a stainless steel valve in one of them controlled by a clock spring, that looks exactly like that choke spring, except heavier duty. It's job is to restrict the exhaust on that side, forcing some of it to travel up under the carb and over to the other log manifold. Of course this exhaust is about 400*F so it heats up that area around the choke well,in addition to heating up the carb. As it heats up the manifold and thus the choke coil, that coil opens the choke plate.
So if the passage under the carb plugs up with carbon, or the heat-riser spring is missing or the valve itself is seized or MIA, then the choke coil never gets warm enough to fully open the choke valve.
By your picture, this choke coil is not electrically assisted, so, forget I mentioned choke-timer for now.
