When dissembled I loosened the adjust screw until the motor turned freely by hand with out resistance or clicking the diaphragm. when completely assembled i turned the adjust knock a few clicks at a time until the horn was at its loudest and not dragging or stalling the motor.

well in looking through my parts i noticed that my Clutch Adjusting Eye Bolt was bent, and some of the threads are gone, even chasing them did not cure the issue. Hard to get nut to go passed a certain point.

Stock Clutch Adjusting Eye Bolt

So i went on a venture to find a replacement, which none to be had, so I had to make one !!

I looked at standard Eye Bolts, noting that the stock one is 3/8-16. Found several options but the eyes were all too large. The stock eye is about 5/8" dia, the ones I found were either .90" or 1.00" diameter. Also the stock eye bolts on the shelf were NOT fully threaded. Then I stumbled across what I needed in the way of a 3/8-16 turnbuckle !! they are completely threaded and have 3/8-16 threads along with a 5/8" diameter eye, granted they are closed.

3/8-16 x 16 Turnbuckle

They have a 10" & 16" turnbuckle, went with the 16" as the screws were long enough, the 10" screws are shorter than the stock, 16" are longer than stock but can always cut them to length.

Marked up Turnbuckle Bolt using Stock Clutch Bolt as a Guide, then Used my Angle Grinder to trim and cut to length, then filed to clean up threads and edges.
