I am glad to know you have the Lambda that way I can reference the green books for my 78 a little.
You are losing me with that 5 degree description too. The crank pulley mark should be on zero for TDC or really close.
More importantly, the mark on the engine casting, that are inside/behind the belt cover, should also lined up to the notch in the belts crank sprocket. That one is true zero or TDC mechanically.
The pulley might be mounted wrong underneath it all. Study the manual about notch alignments if needed.
The dot on the distributors gear face has to line up on the long sheet metal dimple that runs down along to the right side. It's punched inwards. I use a mirror to put my eyes in-line with the dot and tooth. It is a tricky one to get to stay right in place as it easily rotates when tensioned. Do not trust the pointing of the rotor button alone for timing. Use a mirror or you could be off one tooth or that 5 degrees.
You were either on or off now it seems. You can fudge the with moving the distributor on this car if the cam and crank are right.
When I was talking earlier, I thought you had already change the belt and was trying to give you some quick "look it over" references. Setting the belt right is the best and only thing to do if you are suspicious of timing being off.
Vacuum leaks are always a concern. A real lean mixture is never good. Check above the flap of that big rubber boot below the throttle. Make sure its intact, no cracks and is clamped on straight, tight top and bottom. The flap has to be pulled up by air flow. It should only take a whisper or air from the under side to lift it.
As far as the advance numbers you speak of.... there is the initial basic setting of 12 degrees with the engine idling at about 1000 rpm. The rest of the advance happens at higher speeds by some weights inside the distributor or the vacuum diaphragm on these cars. You can only check it with a timing light or inspect the distributor.
What you want to see is for it to jump the mark farther to the left more degrees when the throttle is blipped open quickly.
I think you can only estimate it to be about 27 degrees unless you have a light with the thumb wheel to advance the strobe back to zero and read the difference on it. That number is only from memory but you get the idea.
I built my first advancing light from a Heath Kit many, many years ago. I think they are out of business now.
Harbor Freight now sells them for cheap, IMHO. Mine was still a little better, as it showed the RPM's and Degrees with a release the trigger and I have a circuit board for calibrating it, if that ever needed to be done? I say WAS, as the strobe tube burned out or a transistor. I am not good at troubleshooting electronics, so I sprung for the HFT one to use on my 78, 84, 86, motor home and motorcycles. The 91 does not need one except to check for spark on the wires.
In 89 Volvo and just about everyone else went to the CPS system.
With coils on the spark plugs engine of today, they may be museum pieces of equipment, someday?
As far as pressure points the K-jet is rather demanding to use that set up to know what is what, unless you throw parts at it.
If it's running, I like to blame the fuel injection last on these cars, unless it has had bad fuel. Like in really old gas and it set a lot!
That will kill any car!
I bought the gage set (recommended by Lucid) from a on-line discount tool house for about 85 bucks shipped since I was a new customer. There are deals out there, as they might go the way of the timing light, or not, if we keep using gasoline.
Later on, or sooner than we think, it's going to be about who has the newest & fanciest volt/amp meter with fuzzy logic algorithms to predict battery failure!
Oh, maybe they are going to built in!
Then the question will be, do you need a mechanic for the tires, cooling fans or turbines, a solid state qualified fuel cell electrician or a computer guru?
Tell your kids to start buckling down in school or its throw away time even bigger for them too. Designed right in, all over again! They will never stop paying rent or leases.
No greasy hands....how could some one really live like that....yuck! (:-)
We should have been there 25 years ago! IMHO
That would have been when I was working and could afford it to go fly with the HYBRIDS!
