according to my haynes manual vehicles equipped with tfi-iv ignition system, unplug the single wire spout (spark output) signal connector where it goes into the tfi/icm module harness connector.

How do I adjust the timing on my TFI dist. ? The book does not say how.

Do I need to disconect anything to set the BASE timing ?
Buy Haynes and search, or

Warm up the engine

Find the SPOUT valve;



Pull it out, the revs should drop a few hundred rpms

Aim timing light at balancer and take initial reference to go back to if need be.

Realize the harmonic balancer is unreadable

Stop truck, clean, paint and detail balancer timing marks, start over

Check and record initial timing

Loosen dist clamp and turn dist until 13.5 degrees is reached

Tighten clamp, re check timing with light

plug in SPOUT

Go down to aftermarket speed shop order MSD coil, Taylor wires, new cap & rotor and the cheapest Autolite plugs you can find

Gap them to .055 and install them

Sit back and wonder why you didn't do this the day you bought the truck

Kick yourself for the money you've wasted on gas you didn't have to buy

PM Sixlitre and thank him

Oh, didn't know you could unplug the SPOUT with the truck running, thought it only made a difference when the truck was restarted. Wish I had known that today lol, checked my timing just to make sure it was at 13-14. Woulda saved a start up lol.

I hooked up the timing light with the spout still in just to see how far it was advanced at idle by the computer, and as i was watching it, it was actively changing it, was anywhere in the 10-20 area everytime the light flashed. I figured it would just make small changes to the timing, never thought that it would be actively manipulating it like that... not that it really matters, I just thought it was cool.

Didn't know that either. Maybe someone can set us straight as to whether it should be shut off first or if it should be pulled while running

Yeah all we need now is if we unplug the SPOUT while running or not.

I wouldn't disconnect the SPOUT while the engine is running. Not because I believe it will harm the ignition, it's a safety thing to me. I don't get my hands anywhere near the belt or pulleys or fan when the engine is running. On my engine the only way to reach the SPOUT connector is to reach up under the belt next to the A/C compressor, which means that you are practically touching the fan as well.

Er?

My spout connector is on the TFI module over in the driver side corner, no where near the engine.

They put the spout connectors on the distributors?

On earlier EEC-IV/TFI-IV systems, yes. They are typically close to the ignition module in either case.

Ah, ok. As for the pulling the spout when the engine is running, I remember seeing somewhere that you're supposed to do it with the engine off, I don't remember who posted it, so I don't know the validity of the statement. But I also remember them saying that you should only start with the key, and not to use a remote start switch, and they were fairly adamant about it, saying it would throw off the timing or something. Not that I know how it could, I just remember them saying that.

I guess you didn't look at the photo posted by sixlitre, it's completely obvious that the SPOUT connector is not on the fender in that photo. I believe it was 92 when the TFI module was moved off the distributor.

That sneaky [email protected]$turd Sixlitre

threw a wrench into the whole thang and gave him the only SPOUT valve pic he had, which happened to be on his econo-commuter, his Lincoln Town Car.
