Had (well, still have) a hot start problem.

Fair enough. The primary problem here is that, being fairly new to mucking
on cars, I'm really not sure what to look for.

Gotcha.

What's a suction hose? :)

This is the point (were I on the clueful end of the conversation) where I
would tell me (the guy on the other end) to RTFM. The tricky bit is
finding out just where The Fine Manual lives. Given that I have a /basic/
understanding of how an engine works, and don't mind mucking, what (aside
from the DMC tech manual) should I be Reading? Not necessarily DMC
specific; more general theory (ie, this is how a brake system works, this
is how a cooling system works), what procedures to follow when
encountering certain problems, etc. I can dig up resources with google as
well as anyone, but not everything on the web is true (say it isn't so,
noah!). Finding *trustworth* sources is hard. <meta name="trust"
value="high"> would be nice, but I don't see it happening any time soon.
:)

I always feel like a tard when I need to ask for answers to what I know
are ridiculously simple "I should have known that" kind of questions. I
don't have any problem with learning; I just need to know where the
school is. :)

Thanks as always.

Impossible, sir. It's in Johnson's underwear.
