Just bought a new horn, and I'm wondering about valve compression and what is considered "normal". The first Valve has an audible "pop" when I pull out the first slide then depress the first valve. (I assume this is an indication that the compression is good?). However, when I do the same with the third valve slide/valve, the pop is Much less pronounces (very little "pop"). Also, I can "feel" the first valve slide wanting to spring back when I pull it out without depressing the valve. Not so with the Third valve. Since it's a new horn, I just wondered if this is unusual or something to be concerned about. The horn plays fine and I don't notice any issue, so my only concern is that there could be an issue that would show up later... THANKS!
