Did they show a purply-blue spark when tested out of the engine? That's the
key. If, in a dark garage (or at night), the color is anything but purply-
blue, then it's weak. And whay is it weak, well, it appears to depend on a
number of factors.

Good question. It's a certain number of startups, but I don't know the
number.

Thanks for the attribution, but I think you and your friend pretty much
solved this one on your own.

You also appear to have had multiple problems, some of which exacerbated
the effects of others. This makes remote troubleshooting difficult.

This thread (and the issues it has highlighted) has given me a couple of
more ideas for the "start problems" page, which is in the middle of an
extensive rewrite.

They were the plugs that were already in the original engine, which HAD been
running before we took it out. They were nice and clean and like I said,
"bench-tested" fine. The plugs that came in the replacement engine were
extremely fouled, which is why we swapped them out in the first place.

It was a nice thick blue spark visible even outside in the bright daylight (but
still under the shadow of the hood).

Heh... it makes local troublshooting difficult too! But I know what you mean, a
lot of times when you're there in front of it, you may see or hear or notice
something else that gives a clue you won't get remotely. I have the same
problem all the time doing remote (phone/IM/email) computer support - something
that may take an hour on the phone could be figured out in 5 minutes sitting at
the machine.
