Regulator repair?

I've got a 1980's Ruud gas furnace that quit on me. The blower runs great, the pilot is running fine, but the regulator occasionally won't pop on by itself as of this year. However, if I give it a gentle tap there's a "sproing!" springy noise from the regulator and poof, it comes on. Do these get dirt in them or anything that would clog up the spring?

If so, can I replace the spring and have it running fine again or do I need to find a whole new regulator?
Thanks!

Regulator ? Do you mean the gas valve ?

I would never leave an intermittent/sticking gas valve in service.
I don't recommend any service on gas valves or gas regulators.

Gas is not forgiving.

Yes, the gas valve. Being so old I worry I won't be able to find the whole valve with the associated plugs for the CO detector etc so if I can rebuild it I'd sure be happy.

No, gas valves are not rebuildable.
That unit is older, the heat exchanger should be checked before going any further.
I donít know what you mean by plugs for the CO detector.

It's probably a flame sensor and not a co detector. One right outside the flame area and one at the start of the vent.

Those sound like the limit and rollout.
Take your meter and start diagnosing the issue. Rebuilding the gas valve is not an option.
