Looked in the archives under "throttle switch adjustment" and got 5 hits in
11 years.Must be doin it wrong.Still got the symptoms and cant figure it
out. Should pull  ok  a bit under 2000rpm,but it bucks. Especially in lower
gears.Sometimes bucks at 2300rpm.

Tried the timing and readjusted the switch. I will do this again, as when I
did the search, I found some interesting info. The gap of .002-.004 is to
be set as the switch closes.You want the switch to close at .002-.004 as
the throttle returns to the idle position.Not by just putting a feeler
gauge between the throttle stop and screw,and setting the gap to .002-
.004.As Spock would say,"interesting".

At impulse speed, in a parking lot,I am not having any fun.Seems something
is out of adjustment.I checked for tribbles in the engine compartment and
didnt find any.The transmission cant take much more of this.Any of you Star
Fleet mechanics got a suggestion?
