For right now, my money's on the weak spark.  I'll be replacing the cap, rotor, points, condensor and the coil as soon as they arrive (hopefully soon!).  If it's still week, I'll do the wires.  After that, I can't think of anything else accept the distributor itself.  Can you?

I've changed the points, cap, rotor, coil and 3 out of the 4 plugs.  Why only 3?  There is no way humanly possible to reach the number 4 cylinder plug without removing the manifold.  At least none that I can see.  Hense my latest concern.

 

Will it bother the engine to run 3 new plugs and one old one?  The old one has carbon buildup on it because the engine was running rich.

 

I don't know if I've cured the running rich problem, but I might have.  The engine idles high now, even though I didn't adjust it.  The only thing that I did was add the new components, the coil being perhaps the most significant.  My suspicion is that now the engine is getting more spark than it did and the previous setting for a smooth idle was actually running the engine rich.  Now having more spark, it makes the most of all the feul it's getting and is idling faster.

 

It also sounds a lot louder.  It sounds like a motorcyle.  I'm sure the higher idle contributes to that, but I wonder if getting more spark (if indeed that is the case), this thing has a bit more fire in it and now exposes the true agedness of the muffler.

 

So again, please tell me if you know if having that one old spark plug in the number 4 cylinder will screw up my engine.  The plug was new only a couple of thousand mile ago, but running rich has made it black.  Will it burn off?

 

If you know of a good way to change out that plug, please tell me, because regardless of whether or not it will cause any problems, I would much rather change it out.

A Condenser can cause these type of problems too....

they can work for a while and then either play up or stop working...

intermittently....

A fuel filter can block up intermittently too ...

a bad batch of fuel or rust from your tank can do it...

 

There is a resistor in the rotor button in the dizzy that can cause problems too....

check at night to see if there is any shorts in the spark plug leads or dizzy cap...

I bought the tune-up kit from aircooled.net, which comes with a new condensor, but I didnt' put it in.  The one I have is only a couple of months old, but I may go ahead and do it anyway.  Why not?  Everything else is new!

 

I'd still like to get some input on whether or not having an older plug will cause me any headaches, or any tips on how to get that number 4 plug out and in.

Running #4 with an old plug is not ideal, especially since the other are all black, but it won't actually hurt anything I don't think.  To get it out, I use a 3/8 socket wrench with a ~3" extender and spark plug socket.  Maybe add in a universal joint to replace extender if needed.

Do you have a single port intake manifold?  If so, I will definitely try again, but when I looked and tried to get my fingers in there, just to pull off the wire, I found it pretty ding, dang tight.  It doesn't even look like there is room for the wire to come off, but I could try it again if you are saying it's doable.

Nope.  I have a dual port with the Autostick stuff stuck in there as well..  My 1500 single port in the Ghia though was no problem with the same tools.

I'll try it again when I get home.  Perhaps the conditions were not prime when I did the rest and therefore did not have my head in it.  It was cold and dark and my two kids had to hold flashlights for me while I did the work.

 

I wish I had a garage.
