Jim,

I used some Liquid Wrench to loosen the screw, then worked it loose with a screwdriver laid in the groove sideways. Later when making more adjustments, I used a quarter. It helps if you hold the end of the strut down just a little. If that isn't enough, you will have to loosen the jury strut clamp to lower the upper end of the strut.

what do I have to do to get the end of the strut- adjusting screw, out of the wing to adjust it? Lift the wing up? loosen the jury strut also! off to try it... jim

Re: wing wash adjustment

Pull down firmly on the aft strut while lifting the wing tip and it should come out so you can get to the end of the strut with a screw driver. Be gentle but firm. You may have to prize the upper strut fitting apart GENTLY to help out, and a little lubricant can help also.

Remember that the lever arm of the strut can wreak havoc with the strut attach fitting on the fuselage.

Adjusting the wash out requires a sign off, so I hope you found a new undead A&P.

Re: wing wash adjustment

don't forget to remove the jury strut connection & loosen the bolt at lower end of the strut.

Check the strobe connection wire of the encoder. Most installations require it to be grounded. Without this connection the encoder will not send data to the transponder.
