Holley Elec Choke problems

Greeting friends,
I put a holley 670 street avenger on my SBC 406. With it adjusted all the way long (counter clockwise) the choke works for all of about 2 minutes then dies until the engine warms, then all is great! I got the hot lead from the wiper motor hot lead.
Has anyone heard of such a problem? (cranking afternight)
There has got to be something wrong with the choke mechanics or electronics..... Help.... It's imbarrasing having to crank up at a stop sign with neighbors behind me....
Thanks,
Loren

I'm not sure I really understand your problem. You set the choke as rich as you can, after 2 minutes the choke releases and the car stalls? It's normal for an electric choke to release after a couple of minutes. Do you have the heat track in the intake manifold blocked off, are you running headers or cast exhaust manifolds with a heat riser valve?

The intake is an Edelbrock Performer EPs with Holly 670 street avenger. by and large you are correct. I crank it up in the morning and by the time I get to the first stop sign....<1/4 mile, it starts dying, at least it does crank back up. I did get through to the folks at Holley who suggest putting on a new choke cap (which has the coil in it).. I just put it on, Now I have to adjust it down. currently idling at about 2300..... Keep your finger crossed I can make it past the first 1/4 mile..
Thanks,
Loren

That's what the tech at Holley thought too. I have now replaced the old coil.... You wouldn't believe the improvement, even in smoothness and power.... Who'd have thought?

Thanks and you are absolutely right!
