HELP...Will not idle in gear

Sounds like the timing marks are lying to you.(you did disconnect the Vacuum advance for setting the idle timing,right?) Put some idle-timing back into it, til the idle screw is back to a reasonable place. Then drive it. Keep putting timing into it until it pings;then back it up a bit.
Now go figure out whats wrong with the marks.
Finally hook the V-can back up to the spark-port.
