Let me begin by defining the "marked position" as where the wire for
cylinder 1 would go, if the mark on the new distributor cap is
correct. This appears to agree with the illustration in the Haynes
manual, although because the distributor can be rotated a bit there is
some possible ambiguity in the diagram between two adjacent locations.
If Top Dead Center is where the white markings on the engine flywheel
are at the very top of their rotation, then I think I have found it.
It appears to be when the contact on the rotor is 180 degrees opposite
the marked position (Mark+4). However, when the wires are moved to
make that Cyl 1, in the proper order, it doesn't start. Nor does
Mark+5. If you recall, I said earlier that I'd tried all 8 possible
positions for Cyl 1, still no start.
What is odd, however, is that earlier today when Cyl 1 was in the
marked position, I squirted some starter fluid into the carburetor,
and it actually turned over just a bit. In fact, the engine ran
(poorly) for a second or two, but died. That's the closest I've come
to getting it started since this disaster.
So, what do I conclude from this? The fuel pump (or something) failed
independently exactly when I started messing with the distributor cap?
Remember that the engine was running quite well before this. It has
actually been reliable transportation, I've driven the RV thousands of
miles and it's never left me stranded. The gas is not suspect, it was
just purchased a few days ago. I drove it 100 miles on that tank, no
problems.
My hypothesis now is: Put the wires back to the Marked position, leave
them there. Look for possible unrelated problem (however unlikely this
sounds).
