Re: holly choke

Check for power on the fuse side where you hooked it up. Turn the key on see what kind of voltage you get there.

Re: holly choke

Many chokes have 2 wires - mine does. Make sure you hook them both up. One goes to power and the other to ground.

Re: holly choke

That is a perfect connection point for the 12v source. You will have to check it though to make sure it is providing 12 volts. I believe in the middle of the fuse box there are 3 male connections spades. Try another one.

Re: holly choke

I had mine hooked to the 12V supply for the windshield wipers. You have to turn the key one then pat the gas once for it to close.

Re: holly choke

ok I will check that , so would it hurt to put a inline fuse and just run the wire off the battery or is that a bad idea?

If you run it straight to the battery it will work one time and then never again. If you never remove voltage from it then it can never reset as it is a thermal element.

Try hooking it to a switched source again, turn the key on, and then move the throttle by hand or by gas pedal to see if the choke plate shuts. Once started and running for a minute you sometimes have to pat the gas again to get it to open back up.

Looking directly at the choke connections, ground is the left and +12V is the right.

Re: Holly choke

ok I found a 12v source that resets when the ignition is off, my car will run good if you hold open the choke butterfly when you release it the engine chokes its self out, how do I go about adjusting this I think the butterfly is not opening up far enough

Sounds like your choke setting to too rich. If your sure you have the 12v problem solved, loosen the 3 screws that hold the black cover on the choke and rotate the cover I think clockwise. You have reference makings on the top so you can see where you started if you have to put it back there. This is where you adjust your choke to how fast it comes off.

Re: Holly choke

As you turn it you will see the choke plate open farther(leaner). Remember if you are trying to set it with the 12V applied, time is working against you as the element heats up. I disconnect the 12V when trying to dial in the choke then reconnect it when you are sure you've got the initial choke plate setting where you want it so it starts right up and fast idles.

Polarity is important! Here is a link to Holley information on installing the choke - http://www.holley.com/data/Products/...199R8000-3.pdf
