Ken:
Your timing still sounds retarded. It is possible the retard
unit was damaged,
or is not releasing when the vacuum is released.
Check the function of your retard unit by fully warming the
engine, and
then removing the vacuum connection. The idle speed should rise
immediately
by 300-500 RPM. Anything else means something is broken.

Comrades,
Recently had the unfortunate occurrence where the dizzy revolved approx.
45
degrees ccw
when cruisin the local interstate. The vaccuum retard unit prevented it
from
turning further ccw when it butted up against the block.
Replaced the points/condenser/rotor/cap/wires and spark plugs and
re-timed
engine to
10 degrees BTDC @ approx. 900RPM (w/vacuum retard unit disconnected and
plugged) but engine still will not idle or accelerate smoothly.
Have very noticeable stumble upon acceleration with backfiring with
'popping'
sounds coming from exhaust on deceleration. Also need choke out to
maintain
idle speed and accelerate from stop.
Any chance I caused engine or vacuum retard unit damage when the dizzy
revolved ccw?
Any and all opinions are definitely welcome.
