Still struggling with car at idle after 8 years

Research… Please google the model and it should show what’s required. Dancing around here when we need to nail this down.

Minimum 1.5 ohms coil.

I have a 1.5 resistor and a 1.5 flamethrower coil installed. Dont really think its the stock resistor. I believe previous owner changed it.

Ok you are good on the coil. It was upside down and we could not see that. I am sure the resistor is good as well.

What you need to do next is pull the red wire off the coil (looks like that is where it is) and put it on the resistor side i showed. That gets you full

12V from the ignition sw. Yes it can run that way but not correctly.

The Pertronix instructions are not clear for your Z as its written for all 12V negative ground cars.

The term crank and run are not the same. Cranking is turning over the engine to start.

When it starts, then it is running.

You will have to get a twin connector to replace the single connector on the resistor side with the black/white wire.

Those two wires get connected to the same side of the resistor primary. That is the 12V from the ignition switch.

Do this and hang on when you drive it.

Can you make a drawing or use the pictures i sent you to indicate exactly which wire i need to remove and where should i place it? 

What type of twin connector? i get lost here, sorry.

Thinking about that red wire, it come with an eye type connector.

In that case all you would do is remove the nut on the resistor where I showed the arrow previous above.

Put the wire over the post and re-install the nut. Keep the black/white wire as it is now with its the spade connector.

Here is what you want it to look like.

Ill try it that way and revert. However, what will happen if instead of using this old resistor i get a brand new and a 3 ohms pertronix flamethrower coil?

Please bear in mind that if i use this 3.0 ohms i will not be able to get an accurate reading in the tachometer.

Don't change two things at a time!!!

Make the change Gundee suggested and drive the car! Only one change at a time. Always!

NO!  Do not do that. Do not revert. Do not try anything else.

The 3 ohm coil is different wiring.  DON'T.

Gundee,

You really nail it! Now its totally different. More speed in first gear. Now its a real racing car. Ill check the spark plugs and revert.

Hang on…Wait until @gundeegets back to you. Slow down friend.

I took some pics of the plugs 6, 5, 4, 3 and 2

[Yarb]

Don’t think you’re going to get a clear picture until you clean those up or replace them. I assume these are the same plugs that were in there before the change was made. One variable at at a time. Otherwise you won’t have a clear idea of what’s happening. IMO

[Mark Maras]

 @jalexquijanoI agree, time for new plugs. How many turns down are the carb nozzles now and how much better did it run?
