Thermoquad fast idle loss.

[Charlied]

About four weeks ago set up fast idle and curb idle. I got it dialed in perfectly and worked fine. Then yesterday after sitting for a week fast idle gone and had to feather the throttle to avoid a stall. The carb was never touched. The battery is weak and need to replace soon, would that have any impact?
Secondly any suggestions on a new replacement carb, Holly, Edelbrock ? I’ve carefully rebuilt the TQ twice, but getting tired of its reliability.
Thanks

Sounds like the choke is not closing.
