Horn

have you tried the adjustment screw on the back of the horn? sometimes your just one click away from a working horn.
 
Bikejunk hits it.
If the motor turns the rest is pretty simple. Half the fun is fixing things.
I wouldn't send it out. The motor drives a big gear with tips that hit the diaphragm. As the motor spools up then down you get that sound. You may just need to turn a screw.
 
The motor spins and I have turned the screw on the top.
i want to use it on my Ardun flathead that is 12v.
Could that be the problem, spinning to quickly?

No. Are you certain this is an original Model A Sparton-type horn?
 
Not sure, I have had on my shelf for over sixty years. The back cover was replaced with a tin can that was soldered to the body.. Just decided to try and get it working.
Can not read the plate that is in the horn.
 
Good. The originals are pretty simple, and it sounds like you have an original. Good reproduction motor covers are also available through most Model A Supply shops.
 
It makes noise,but not the ahooga{spelling} sound I was hoping for.
Just a steady noise. My wife says it sounds like a sick duck.
 
One click on the adjuster can make all the difference in the world. It may still be adjustment that's keeping it from sounding right. I would keep messing with the adjustment before I sent it out for a rebuild.

If your using it with 12v youll need to get this http://www.ebay.com/itm/12-Volt-to-...Parts_Accessories&hash=item4d23add19d&vxp=mtr, or it will sound like a scalded duck. Mine is on 6v and I adjusted it but it never sounded right till i took it all apart and cleaned and oiled it and removed rust from the diaphragm. Now it makes the proper sound.
