74 choke question

[Robin7TFour]

Hello, on the 74's did they come with a heat-tube to activate the choke? or were they electric? if so,what color is the wire(s) that get the coil working.


thanks in advance

Neither of the above. There is a bimetallic spring inside a metal 'stove' on the intake manifold that unwinds, pushing on a lever to open the choke as the engine heats up. It's located on the passenger side of the manifold, directly below the choke lever on the carb.

The electric choke on your Edelbrock needs a full 12 volts - don't connect it to the (+) coil terminal, as that only gets 7-8 volts with the engine running. Best bet is to run the choke wire through a firewall grommet and connect it to the fuse block cavity marked "Ign".

John , we do think alike. since my car's been butchered allready i have plenty of 12v sources. the ground will be a simple jumper from the choke to one of the carb studs.
thank you again .i look forward to your input anytime. btw why is there a Ferrari poster in your garage?
