The stall horn in my old C150/150TD used to go off well above stall speed, even after adjustment.
It somehow became disconnected.

Now is more like 10mph when it goes off before the stall.

Sounds familiar. The template supplied by Stene to relocate the opening for the stall Warner is open to some interpretation. Quite often to get the unit all the way to where you want it may take the careful application of a die grinder.

Anyways sorry for the thread drift. Once I get the new engine installed on my airplane later this month I'll prolly see you over some of those gravel bars, looks like fun!
