First, I use a drop spreader rather than a rotary spreader since I
don't want the herbicide to hit the plantings bordering the yard.

So here is my paradox.
The Scott's weed & feed says to wet the lawn before using
(presumably
so the herbicide granules can stick to the weeds better). However,
when I wet the lawn, some wet grass inevitably ends up running
against
the drop-feeder slit which causes the fertilizer to cake-up and
clog
the slots.

In summary:
1. If I don't wet the lawn first, then it spreads but it doesn't
stick
to the weeds, so the herbicide doesn't work
2. If I wet first, then the drop spreader slits clog and I get
neither
fertilizer nor herbicide action (or I end up opening the slits
wider by some random amount and get a random, uneven coverage)

So, what am I doing wrong and what should I be doing?

I'll tell you what, and this is the truth.
NEVER - use a weed and feed product. The weed part, as you
mentioned, is a herbicide. It can, and does far more damage to
vegetation, including trees and bushes, that all the feed in the
world does good.

I can think of no worse product on the market, and people fall for
this hook line, and sinker.

I'm not trying to diminish your problem, but please check with a
master gardner in your area before using this terrible product.
