series 3 troubles

G'day.

i've got a series 3 with the 6 cylinder rover, and i'm getting some rather
odd symptoms. the motor is in excellent condition, done well under 100,000
ks, runs beautifully with no smoke etc. but occasionally, generally in cold
weather, it will start running like a dog for a coupl of minutes, then jump
back to normal. when it happens, it wont rev past about 3,000 (no tacho, but
thats my guesss) and feels like the timing is way way out. my suspicions are
either a sticking vacuum advance, or the carby float level is not working
properly. either flooding it or running it too lean. any other suggestions??
doesn't stop the car from running, just very annoying when it happens up a
hill and you can't get it past 30ks an hour.

any suggestions welcome.

Sam.

Have you changed the fuel filter recently? Sounds a bit like fuel
starvation at this distance.

mmm, possible. but some blockage in the fuel lines seem like the most
propable to me. as a stuffed diaphragm would probably cause it to run badly
all the time wouldn't it??

Some recent developments.

problem got worse today and ended up dying completely on me. i managed to
crawl home in first gear annoying the hell out of those behind me, but hey,
im allowed to in a landrover, right?

anway, got it home and checked fuel supply. as i didn't have a helper, about
a litre of fuel gushed out of the pipe when i flicked the switch, so the
problem isn't with the fuel supply. had a look at the dia-bloody-fragem,
looks OK. i chucked one of my old volvo strombergs on it, fired up all right
and was running pretty rough, but better than with the landy one. i reckon
it would run very rough as it's tuned for a twin-setup on a volvo and has
been sitting on the shelf for about a year. so i'm thinking the problem must
be with the carb somewhere. i'll pull it apart and chuck a kit through it
and see whether that improves the situation.

will keep you posted guys.

Thanks.

Sam.
