Hello all. Finally getting some time to practice again. Finally got the Magnakeyer hooked up and really like how the paddle works. Find it easy to use. Having a lot of fun with CW! One question....I see it came with an Allen wrench and I see the four Allen screws, 1 on each post and 2 in the back. The left key occasionally hangs up. I wanted some advice from those more knowledgeable, as to what screws adjust what, as this is my first paddle and I don't want to bugger it up and get it totally out of whack! I would think that the screws are right hand thread. I have to go out for awhile, but, will be back later. Tnx for the help! Charlie.
