727 Kickdown Linkage Adjustment - HELP!

Well, I readjusted the rod at the carb so there was about 1/8" of play at WOT. While I was under there, I hooked up my timing light, and the timing at idle, no vac advance was at 10º BTDC. I left it there. I adjusted the front brakes a little and took it for a ride.
The trans shifts 1-2-3 and it won't kick down at all, so I put it back where it was.
I also seem to have a slow speed misfire now. I guess I fouled the #1 plug with the old fashioned timing light.
I can't win with this frikken car, I swear to God.
Thanks for the help anyway Guys. I appreciate it.
I was gonna take this pig to Lebannon Valley next Saturday, but now I'm afraid we'll end up walking home.
