Just to show what the Kommando dash is going to look like. Quite different from the original!

Another question please biggrin

What are the Red, Blue and Yellow ringed items and their function?

73SC · A Poncho Legend!

Having a hard time seeing the parts. Yellow ringed item is for sure an idel stop solenoid, an electrically operated plunger that provides a predetermined throttle setting at idle and closes the throttle completely when the ignition switch is turned off. Also known as antidieseling solenoid. You can probably live without it. If you keep it you will need to attach a keyed source of power to it.

Looks like you have a computer controlled carb there. The red circled plug is the MCS solenoid (mixture control solenoid) and the blue circle is the TPS (throttle position sensor) not sure how well it will work on a non cumputer controlled engine. More info on this link;

And so it is!!! However I noticed that the air screws have been fitted and blanked off.
Is it possible to remove the air mixture solenoid, open the air screws again and make the carb work?

I have been offered a standard Quad in working order for $60 Just need to check the number on the case and then order the kit just to make sure!

Good question, I have never tried this. I would go with the standard one if you can get one. Would be a shame to spend money rebuilding a carb that might not work in your application.

Here is a site explaining how to ID the carb from the part number;

Thanks for the comments. Will see what happens tomorrow! Hope things work out. Can always order a kit for the standard one (4MV) and have it re-furbished!
Kit is about $10 less than the electric carb!

Here are pics of the work I did on the motor this weekend. Can somebody tell me how to wire up the HEI distributor to a standard system?

Oh boy, how bad is it, will it repair easily? Will you need any parts sourced from here?

Looking good Johann, Just need a keyed 12 volt sorce. Must be 12 volt and not run though a resistor.

Not too bad.

Well that sure sucks now after you have the car just the way you like it. Was it a hit and run or were you around to see them? Otherwise how is insurance to deal with over there? Good luck with it.

The only thing I would add to the wiring answer is I would make sure it is a fused wire.

Thanks Carl,

There are three wires coming out the one side and four wires out the other side and the Coil has three wires.
How do they come together? They are all hangin loose!
The live wire for the coil from the ignition is there.
I am used to the good old system of vacuum, points and condenser confuse

I don't have an HEI at home to post a pic and explain. If someone does, that would be the easiest.

I was in the car, No insurance, he apologised and is paying blankstare

Hullo Carl, I am sure some Poncho will be able to assist.

9000!

So your ready to wire up an HEI? Heres the summary in a nutshell;
Replace the resistance wire that ran to your points system, from the fuseblock, with a 12guage wire (pink insulated if you want to remain factory compliant) and hook it up to the HEI "BAT" terminal. Thats it! Easy, Eh?

cdnpont · Canadian Poncho Superstar!

Johann,

I think what you have is a later style HEI dist that has a external spark timing (EST) control connection (the 4 wires). This 4 wire bundle and their connector would tie the distributor control module to the ECM. The ignition spark timing would be controlled by the computer.

The 3 wire bundle will be the standard connction to up to the cap. Red, Black, Brown? Or 12v in, ground and tach to coil.

Not sure if you can use this dist without a ECM? You might need a earlier (73 to 82?) vacume and mechanical advance HEI. Should be easy to find one though

Sorry Mate Hes correct I wondered about all the wires confuse

All the ones I have used have been 3 wire as well wink

cdnpont · Canadian Poncho Superstar!

If you do not have a Vacuum or Mechanical advance mechanism on your dist Johann, then you have this type...

When vehicles went to full computer control of ignition timing and fuel mixture beginning in '80 or '81, a seven-terminal module was used. This is termed HEI/EST (Electronic Spark Timing) These distributors did NOT have centrifugal and vacuum advance mechanisms, all timing advance was pre-programmed into the computer, using information from the entire array of engine sensors. Base timing could be adjusted, however.

Beaumont4008 · Uber Guru

These guys are spot on. You will need one with a vacuum advance like below. The three wires hook into the cap as below and and the 12 ga goes to the bat. terminal on the cap to a keyed 12 volt sorce. The three wire plug can only plug in one way. If you need a pic with out the cap on let me know. O yea the paper on the right is my collision estimate for my truck $2400.00 for the wife hitting the garrage.
