This is the first time I've ever had issues with the choke, I think it's time to rebuild mine again.

Does it have an electric choke or one with the spring and rod attached to the manifold (divorced choke)?

If it has the divorced choke, do you have a working exhaust crossover that heats up the manifold or is it blocked off? If it doesn't have one, it could never be getting hot enough to release the choke fully.
