My horn isn't horny enough. About every fifth or sixth time that I honk it, it wonk honk. It seems to depend on the point where the silver part in this picture halts its spinning. If I gently nudge it about an 1/8 inch, it honks perfectly for several more times until it stops in the dead zone.
Any ideas on why this happens and a remedy?
My guess is you have a bad connection of the winding to the commutator bar
