Default Problem Horn

I have a horn that looses it's adjustment often, especially during parades. How can I keep it adjusted to the ahooga sound? Is my problem a worn Horn Motor Diaphragm or...........?

Also the horn does not seem the correct ahooga sound. Is this a bad Horn Diaphragm?

Any suggestions or words of instruction would be really appreciated.

I would say that the screw or the hole is stripped or the threads are not that good. You could try some LIGHT DUTY locktite on the screw to keep it in place if you do not want to fix the horn now, but you probably will as it sounds like there might be something wrong with the diaphragm.
