Outer Limits 4x4 Board

Ive got a 76 Rangie on dual fuel. But runs rich on fuel. It appears the carby needles are worn. has anyone had success with replacing just the needles and not the jets (as I suspect they are also worn)?
Cheers Euan

I've always been confused by this issue.
How do needles wear?
They don't don't ...

The locknuts I used are called "Barri Nut".

They are keyed, and you need the included socket thingy to tighten.

Hi all i have a 1981 2dr range rover and after removing some wires that had nothing to do with or connected to anything i now only have full beam when holding the stick back. This also has duel batteries and a 4.4 p76 engine in it if makes any difference. any help is good as i keep missing out on ...

1) When I select HI low beam stays lit - this will lead to buld burnout I guess due to heat.

Is this supposed to happen? It does in my Rangie

I am pretty sure that's wrong, even in a rangie. It's certainly not right for 99% of vehicles - it should be high beam OR low beam, not both. Especially ...

Blown globe?

IMO, headlight "upgrade" looms are a waste of time and money (i've fitted four).

IMO, headlight loom upgrade is fantastic. I made my own and it dramatically increased light output.

The best band for your buck lighting mods IMO are:

- Upgrade your stock H4's to "Arctic Blue", or a "whiter" type ...

Great build up.

Now I can see the difference between shocks everyone raves about.

Great tip on the spring locater!!

My spacers leaked a little till eventually I had to pull the thing apart (burnt exhaust valve) about 5 years ago.

Put it back together with new gaskets and gasket goo.
Never leaked since!

(had to fabricate spacer to manifold gasket - wasn't going to use a 3.5 valley gasket)

Yes it can be done.

Have to remove the crossmember. Mine needed a bit of persuasion.

The whole unit is very gearbox end heavy.
I attached a D shackle to the bracket on the RHS of the transfer case.
Lifted from 2 engine lifting brackets and this gearbox lifting point.

There is a hook on the LHS ...

P76 (and rover) pistons are recessed.
Not sure why, maybe for piston/valve clearance.

The amount of recess determines the compression ratio.

If flat top pistons are used, then the compression ratio is increased.
This will also reduce valve to piston clearance.

Increasing the compression ratio ...

Here's a couple of videos of tracked LRs

OK, scanned the fuel system section to a pdf (2.5MB).
Don't know how to post it to here, so send me a PM with your email.

My 4.4 has twin SU's so I can't actually see the items you are talking about.

However, I have a P76 workshop manual.
I'll scan the fuel system pages for you.

Hopefully I can post a pdf.

I reckon the yellow one looks like a mighty boy on steroids

hey guys,

i have a 97 disco 3.9 V8i....
IT WONT START

a couple of days ago it was running fine and now nothing.
it has fuel, spark and battery is good, it cranks and cranks but wont turn over

any ideas that could help???

If it has fuel & spark & air, then it's timing.
Well that would be my ...

Yep, 3.5 engine # next to dip stick.
P76 has the engine # at the back of the block near the left hand head.
You need a mirror to read it.

Im a sparky and do a fair bit of solderng and I find even the dirtiest of copper is easily soldered with the correct ammount of heat.

I'd disagree with this statement.
To get a "heat bridge", the wire must be clean to enable it flow throughout the cable strands.
Solder will not stick to oxidised ...

Why not leave it where it is, and don't collapse it

Both the fuel and temp gauges are supplied from a voltage regulator.
It's the metal can thing located in the instrument panel.

Mine displayed similar symptons a while ago, but it ended up being a fuse.
Have you got reversing lights?
(same fuse)

Now all i need to find is someone selling unassembled kits at the price I know they can be had for....

Jaycar had a kit a few years ago.
It basically allowed 3 set points to provide a very basic "curve".
Essentially you lock your dizzy to full advance, and the box then retards the spark ...

I've got some pics of 3 gearboxes.
All are LT95s from various sources.

I've done the reverse.
I had a 3 bolt that had way too much slop in it.
So swapped it for the manual one I had lying around.

The input shafts are different. The manual has the flexible joint, and the ps one didn't.

Make sure you get all the brackets including the pump brackets.

Mine was quite ...

Got the coil packs.
Working on getting the leads and connectors.

Still not sure whether to megajolt or megasquirt, (I'm still running carbies).
Megajolt has only 1 ignition map, which is painful for dual fuel.
Although it's heaps cheaper.
Should just bite the bullet and MS for later expansion to ...

I think these are the spacers I have (however they are not wedge shaped. they have parallel flats).

Mine are bolted to the head with allen head screws which are countersunk into the spacer.
You use the P76 valley cover between the head & spacer.

Then the manifold is bolted to the spacer, however ...

I'm lost.

Do you want straight gas or efi?

If it's straight gas, then the efi manifold/injectors/fuel rail/pressure reg etc etc is wasted money.
Bolt on a throttlebody, or even use the standard p76 carby.
It's only an air flow controlling device.

If it's efi you want then what have bought is good ...

there were some Wedges or spacers available once, cost a motza however.
They were a lot of bother, always leaking, vaccum leaks.

They don't leak if fitted correctly (properly sealed).

If you are going straight gas, then why bother with EFI?
Dual fuel yes!

Maybe injected gas. Now that would be impressive.

As far as wiring goes get a relay, wire it to the batt if you want it to cool the car after you've taken the keys out (remember this way the fan will run until it's cool, very annoying at 1am!!!)

Why do people do this?

Having the fans on while the engine is not running does stuff all.
All this ...
