Not sure that I understand, but will try to help. The choke when cold should not open fully (but spinning the choke housing enough should make it open, but would render it useless). The current going to the choke spring (inside the housing) heats the spring, making it expand, then forcing the choke butterfly open.
It usually takes me a couple days to get an electric choke fully dialed in, as they're impossible to adjust once they get hot.
I thought that for it to be in proper adjustment, the butterfly was just slightly open when cold. When I adjust it, it never opens at all even when I turn all the way both ways. I thought the theory was that the choke allows more gas than air until it gets warmed up and then it opens to allow more air into the mix. It seems in my case that it is not allowing any air at all-which is why it won't start.
ok, now I get it. Yes, the butterfly must open slightly or it will suffocate the engine. Been a while since I worked on a Holley, but IIRC, the spring is supposed to fit into a slot inside the housing. If the spring isn't in that slot, rotating the housing does nothing.
You'll probably have to R&R the housing for at least an inspection of the spring and the lever it acts against. Hopefully someone with more recent Holley experience will pipe up here and correct me if I'm wrong.
Hi, just did mine this morning The spring has a loop wound in the end of it and it must fit over the arm coming out of the housingit is a real pita to see because it is short and you have to have the cover all most all the way on to engauge it. If the spring doesn't have a loop or is broken you will have to replace it but double check to make sure it is engaged before condemming it. John
