Yes, until the carbs fill up, then the pump will shut off till the level
in the carbs drops and relieves the "back pressure" on the pump, at which
time it will again pump.

No, The pump power is supplied by the same fuse block connection as the
ignition, and when the "start" is engaged no higher voltage, amps, watts,
or smoke is sent to the pump. It may be that, due to the draw of the
starter, actually LESS power gets to the pump on starter engagement.
