[TR] TR4 and Mallory Dist

[Lee&John Howard]

Very interesting article. I am still fussing with the
adjustment...just finding the screwdriver pivot points took some time.
I've got one set adjusted, but when setting the second set i get no
reading at all. And no combined reading either. So I continue my
tinkering.
Thanks for your help.
