I was trying to tune my son's Satellite yesterday. It is a 1974 318.
It has sat for a year so it is running poorly. The gas is fresh, on high idle it runs fine,but when it kicks down, it will die. I set the idle up a bit and went to check the timing.
As I rotated the distributor, to walk the timing back towards 0, the idle came way down and then the timing light quit firing. Is that a misfire on #1 cylinder? Or was there not enough energy for the inductive circuit to pick up the circuit firing? Never had that happen before.

Can't say for sure what would cause that, I'd say you have an issue going on in your ignition system or your light isn't good, misfire could be the cause.
Why are you retarding the timing to 0 though? The engine will likely not run best with 0 degrees of initial timing, and also if it was on high idle the mechanical advance was likely already coming in (and vacuum if it was hooked up still). The timing shouldn't have moved from the last time it was running.
I would advance the timing and try to stabilize the running conditions first. And let it warm up and get down to idle speed.
For what its worth, stock 2 barrel small blocks even seem to like at least 10 degrees of initial timing. Just make sure once you set it you don't have too much total, it should be around 34ish without the vacuum advance hooked up once the timing is all in. Stock Chrysler electronic ignition?

Yep all stock right now. I swear the book says +/- 2 degrees of timing. But it likes to run at 10 or 12. Glad to hear that is OK. I have vacuum disconnected,

Well, I don't think I have a dial back light. Isn't that what I would need to see the timing mark at 15 degrees advanced?
I think something is wrong with the timing or carb. This thing hates idling low. It is factory 2 bbl and probably needs rebuilt. I have sprayed it with gumout while running and did not notice a change in speed, so I don't think it has leaks anywhere, I think it is gummed up.
I will probably rebuild it this weekend. I don't know anything about the engine, for all I know the timing chain could be off. It is runnign rough.

Yes 15 is getting pretty close to being hidden under the pump. You could cut a strip of newspaper 1" long & use it as a ruler to make a new white paint mark on the dampener clockwise from the TDC slit & bring that new paint mark to zero on the cast in timing tab to get 16 BTDC with the vac adv capped. I had an 80's 318 with 18 & it ran flawless with a dead smooth low idle. EDIT I Googled it & 1 source said 10BTDC for stock timing but it will do better with more. I would remove the mixture screws & shoot a 2 second blast of starting fluid into each carb hole then replace the screws. Count the # of turns so you can easily/quickly return them to their original position.

If the light quit flashing Id be checking wires.They have sat and how old are they?Ive had quite a few bad wires on my stuff and at work.Thats one reason the light wont pick up a signal.Rocky

Thanks gents. I will check the normal tune up stuff first. If I can keep my kid out of the car. Been 3 yrs in the works, he has 3 days to graduation. Making the most of showing it off!
Rapid Robert I am also going to take your advice from the other thread and determine vacuum and idle speed and see where it like to sit. It did not like much more than 10, but the mark did vanish under the pump so I don't know how much.
Thanks for the ideas. I will see if I can work on it tonight. If not, tomorrow and Sat.

Check your ballast resistor as well, been reading up on a surge I have and have seen a fair amount on resistors not holding the proper energy to run them at normal idle. Just a thought do I search and you can see the info.
Careful, your character's showing!

Well, I do have a complete MSD ignition swap planned. Billet dizzy, MSD 6AL, wires, coil, plugs, cap rotor everything.
That will eliminate the ballast resistor.
My underhood wiring was done by a blind man with no electrical tape. Untaped splices everywhere. The ballast reisstor has so many bypasses around it with wires taped wrapped together bare, I am certain if I touch it, the car will never run again!

How much was the rebuild?

here is what I tried today.
Finally found a tach. Holy crap no one carries those any more. Guy at a good parts store said we haven't had one of those in 20 yrs.
Anyway, got a tach, placed on coil wire told it 8 cyl Running around 11 rpm in park.
Placed vac gauge on manifold nipple, did not hold steady, but had a range of 16 - 20 inches.
Timing light on but the mark was gone with the idle up that high.
I placed the car in gear, rpms dropped. I watched vac gauge and turned dist. Got the vac back up to 16 or so. Unlike the 340 from the other thread, my car does not like too much timing.
So, with car in gear I played with the distributor and quit around 15 inches and 800 rpm in gear. Any slower it would die.
WE messed around putting it in gear and and watching rpms. Seemed OK. Kid went in house to get ready for work took mins. The car would not start.
I took lid off air cleaner, closed butterfly and it starts. It seems like my hard start problem is because it is getting too much air. I wonder, since it sat for so long, if the new fuel filter is already plugged. I am going to look at that tomorrow.
This car has a position on the carb when warm, thatthe idle set screw falls into a little notch. It is not spring returning once you open the throttle. I wonder if a spring is missing. Factory 2 bbl. When the idle screw is in that notch, if it dies, it is holding the butterfly wide open and I do not get a start.
