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.

Choke is closed at cold start. Linkage set right. Any chance weak battery could be an issue? As was dead on week ago and never touched.

No.

The TQ is as reliable as it gets when assembled properly. You should check the O rings & plastic cups under the primary main jets [ for leakage ].
'The carb was never touched'. Amazes me how people think a 50 yr old carb should just bolt on & work perfectly without any internal checks....

Send me your TQ when you replace it with whatever else. I'll pay postage.
