Spring Conundrum

Check your centers, check your repetition lever height, be certain of the hammer
rest height. And remember things aint perfect. Sometimes no matter what you do
you wont rid yourself completely of this. Best results are going though the
adjustments a couple two or three times in the same sequence. Another thing to
watch for is what happens to the jack. This is a single spring whippen I suppose.
Sometimes to get the right rep lever lift you end up with a jack that slams back
into the stop button, or is too weak a return for that matter.. Again make sure
all the centers are good.
