Can some one remind me, on the V8 as you look at it from the front, which
carb adjusts mixture on which cylinders?

Getting the old colourtune & gunsons gas tester out tomorrow and hope to get
Morph back rolling.

Good luck!

On a similar note - when you borrowed my spare saab carb to try on
J-Lo, did you change the needle in it?
I've had to raid that carb to get my yellow car on the road (since i
couldnt get the emissions low enough with the existing needle), and it
has a different needle in to what it should have.

Or can anybody point me to an online listing of carb needles and what
sizes different numbers are?
I'm dealing with a stromberg CD175.
the needle should be a B1DS, but i currently have a B2xx. Is this
likely to just be an oversize one for worn needle valves? (I can get
the CO a lot lower using the B2 needle!)

's complicated. I *think* you can tell from looking at a manifold. no. 1
is front left bank, the cylinders are left bank 1-3-5-7 and right bank
2-4-6-8.

the carbs feed 1-4-6-7 and 2-3-5-8, but I can't remember which is which - I
think they feed the middle cylinders on the opposite side, so the RH carb
feeds 2-3-5-8 and the LH carb feeds 1-4-6-7, BICBW.

Nope it was bunged on, worked a treat and whipped off by Dad after sis
got a sparkly new Carb.

No idea about the numbers but if you need any bits can recommend
Mayson and Solomon at Ecceshall, well I think I can anyway ask me in a
couple of hours!

Carbs seem to be ok, I got the CO down to 3.5 and a nice blue flame
with the slightest occasional tinge of orange on tickover. (Colour
tune). COuld have got it lower but rumor has it 101's run better at
the higher CO (by high I mean 3.5%)

Once I refitted all the air filter gubbins CO went up to 6%.

I've yet to check the air filter. Is this normal though? Should I have
set up the mixture with all the air filter gubbins bolted on?

Are 101 Air filters fitted to any other Landie or are they one-offs?

I still think the timing is out and will take a look at this tomorrow.
Reason I suspect this is that when pulling away from a junction and
accelerating I occasionally get some pops in the inlet manifold.. or
is this likely to be cross fire? Got new leads on order from Richard.

Would have been better. Filters will make a slight difference, but if there
is a drastic change then the filter is too restrictive, especially at the
lower airflow at idle.

Don't know.

Cross-firing only really happens if the leads are routed incorrectly and
there is degradation in the ht system. It's actually quite rare, but it's
good practice to route the leads as per the many diagrams in the haynes
books etc, ensuring that 3 and 5 are crossed (5 and 7 separated, that's the
2 that will cross-fire if any).
Pops are usually down to vacuum leaks or fuelling (too lean, or diaphragm
issues) Check distributor vacuum capsule also.

Right, had another tinker and the high emmisions seems to be from one
carb.

I put the gas tester on this morning and ran it initially with the air
filter out , then again with it in. No noticable difference at
tickover.

I checked the carbs with the colour tune and one was running rich.
I'll put it down to teething problems. I adjusted that carb and the co
came back into line. Checked the second carb on the coour tune and
that was fine.

Took him for a run and he seems much better now. Only thing is on a
hill under acceleration he is missing, now I can hear a tic tic tic as
it's missing which last time I was brave enough to run with the lid
off was the plug leads earthing against the block rather than through
the plug. I'll await the new leads and see whats what then unless any
one has any other pearls of wisdom.

The popping - only happend on choke today, once it had warmed up it
was fine. Only popped when I stopped at a layby to peer under the arch
to check the plug leads. Did it's usual trick of waiting till I was in
a precarious position before letting rip with a delayed backfire from
the exhaust... I swear its got a sick sense of humour. (this was after
negotiating the hill where it was missing)

Many years ago I stumbled accross the original lyrics for a well
known Janice Joplin song, which obviously showed she had great
foresight.....

"Oh Lord won't you buy me a Defender One Ten,
My friend all drive nineties,
So I need to make amends,
The old one's worked hard now,
it's been a good friend,
But Lord won't you buy me a brand new One Ten"
