That would be the indicator.
As long as the bi-metal spring is working correctly and opens the valve as it is designed you have smoother less hassle free driving when the engine is cold and it isn't an issue after it is open. The key is that it does work and the valve does move. The counter weight should help it open along with the spring.
If you block it open or even remove it and put a bolt or pair of bolts in the holes (stuck though from the inside with nuts on the outside. It tends to act like headers on other rigs in that the manifold doesn't heat up until it soaks up actual engine heat and low speed drive ability can be a bit of an issue in cold climates. Those of us in the North aka cold winter areas of the world who don't have heat risers spend some time warming the engine up before we take off. Not only to get the heater working so it will defrost the windshield but so the engine will run a bit smoother.
