Carburetor Choke Question

[mr_clean]

I'm going to replace the carb on my K5 and want to know what is the easiest choke setup to hook up?

The vehicle is a 73', but I have the Vortec heads and manifold on it with no provisions for the origional choke that was on it.

I was looking at the Jet stage 2 carb with electric choke, but I don't know if that can be hooked up to a 73 vehicle or not... Should I be looking at a different carb other than the Jet Stage 2?

Any help is appreciated!!!

Thanks,

Scott

As long as your intake has the right flange , or you have an adater plate , you can run any carb you want on a 73 ( take into account any emissions or cfm requirements ) . You need a clean 12 volt switched power wire for the electric choke .

Ok, sorry if this is a stupid question, but what switches the 12v on and off?

Just use a test light or buzzer on the open (unused) terminals on your fuse block. Find one that is hot when you turn on the ign switch and off when you turn off the switch and plug in the wire from the electric choke into that one.

So the choke just needs 12 volts to operate and it determins when it's open or closed?

I was thinking the voltage was +12 for open choke and 0 volts for closed choke...

There is a switch inside it!

electric choke definitely is the easiest route.ignition switch turns on the choke if you hook itup to a power source ran by the ignition switch.it runs like a thermostat opens and closes when it gets hot or cold.

just gotta be careful with electric chokes sometimes, e.g. my friend's old 5.0 mustang w/ electric choke... sometimes he'll rev up the engine some after starting it... the choke will get warm and turn off, but the engine isn't quite up yet for no-choke and it stutters a bit.
