The Correct Way to Wire an Electric Choke

[Stewart G Griffin]

i know that the wire going to the choke will heat up the coil and as the coil relaxes, the choke opens.  What i was wondering was does current go thru this wire as soon as the ignition is turned on or is there some sort of timer.  OR does the coil relax after, say, 90 seconds if in fact current goes to it as soon as the ignition switch is turned on?

It doesn't turn on until the engine builds oil pressure. When the switch closes current can pass through the switch to heat the choke coil. Hot air chokes work off of heat from the crossover as the engine is warming up. Q-jets and dual jets use a choke break to aid in choke operation.
