OK, Curt - I was just quoting the good doctor in the generic causes of hard
starting - and valve adjustment is high on his list. But since the original
message said "valve adjustment 10k miles ago", what was done in this
"nothing to set" engine?

190D Werner, hydralic valves, nothing to set...
Scoff though you might when I left work last night it started lousy...
More testing is needed I think as I'd run the block heater yesterday
morning. Tonight when I leave work I'll loosen the cap.

Curt - I think that its pretty unlikely that loosening the filler cap
at the
tank would have any effect on starting, as there is so much fuel in the
filter, pre-filter, IP, and injector lines - all of which would have to
be
used before any "new" fuel from the tank would get to the injectors.
I would look first at what Marshall has stated consistently: winterized
fuel; proper valve adjustment, working glow plugs. And with a valve
adjustment 10k miles ago, that's 2/3 of the way to needing the next
one!
Actually, if the last one was done just a bit "off", extreme cold
weather
could very well show that up, too.

Actually...
My 190D has been starting harder than I like. Its been cold so I
attributed it to that and bought some Power Service.
Zero difference...
It got so I'd have to hold onto the go pedal and it'd catch but if I
let
off the pedal within 30 seconds it'd die.
This morning I was inspired and opened the fuel cap. Instant easy
start.
I drive an hour each way to work. So the fuel in the tank must be
getting
pretty nicely warmed up. Over night it cools to -1F (or whatever) and
creates some vacuum in the tank.
The engine can pull hard enough to over come the vacuum and pop the
vent
in the cap but it doesn't like doing it when its cold...
Eureka, now to deal with that vent.
