Glad to hear you solved your problem. You will need to check the tightness of the two AN-4 bolts from time to time as they will gradually loosen as the pads wear. Bill Pancake told me that he replaces the pads about every 100 hours or so.

A new flat spring and new wheel bracket post bushings solve most TW shimmy problems.

Most old TW springs sag with age and cause shimmy.

I am having a shimmy issue with my maule tw, after reading this post i ordered a new set of pads from Aeronca.com. My old pads where pieces of baffling that where disintegrating. The new pads helped but the shimmy is still there. So it leads me to believe that my spring needs to be re-arched to. How much? Is there a diagram that shows the arch so the spring shop can bend to a certain spec? Thanks, Andy

Andy,
Make sure the tail wheel axis is pretty vertical or even slightly aft. Add another shim under the spring as a temporary fix.
