Vacuum Pump & Oil Pressure Problem

[frankp]

Chet, good you are confident with your oil pressure.  I've used various 30w oils after my rebuild.  Currently using Shell 30 Rotella.  With the spark, I'm with Ted and follow the manual.

Chet, ...  With the spark, I'm with Ted and follow the manual.

You and Ted are correct in that the Manual states, (Instruction Book P-71, Fifth Edition May 1929)

"To Start Engine

The ignition switch key should be turned.  The spark control button (on instrument panel) should then be pushed all the way in or full advance position.  Except when cranking by hand, the spark button should be set full advance. "

My 2 cents.

Most cars start with a slightly retarded distributor spark and advance automatically by centrifugal force when running.  As time went on vacuum advance was added to push engine power even further.  I would still argue that slightly retarding the timing at startup will make things easier for the starter motor and allow you to push the envelope on the advance side for full or increased HP at runtime.

But you guys are correct.
