Default Spark control 42WLA

I have a reprint of an old War Dept Tech Manual and according to this manual I am to fully advance the timing when starting. It doesn't mention where I should set it after it's started. Should I just leave it in the full advance position or retard it some?

Looking at operators manuals for several years and models they all say set the spark at full or near full advance when starting. The normal position after the motor starts is full advance. They say you may retard slightly when the motor is under load to prevent knocking. Some bikes start easier when the spark is retarded slightly. I would keep it at full advance while running.

That's what I had been doing but it's nice to get a second opinion. Thanks. BTW this thing is a real kick in the pants to ride.
