Ken,
Try 4 degrees ATDC at approx. 900 rpm w/vacuum retard unit disconnected
and vacuum line
plugged. 10 degrees BTDC is for STATIC timing, meaning with the engine
not running. Assuming everything else is OK, that will get you running
pretty well but you should fine tune the timing through small
adjustments on a trial and error basis.

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.
Any chance I caused engine or vacuum retard unit damage when the dizzy
revolved ccw?
Any and all opinions are definitely welcome.
