Runs best at 12deg, everywhere else was rather flat on power.
I have also found another z20s that i can access to see what that is running.
I'll post any results once i have worked it all out.

And by the way, at 5deg it didn't seem to run as well. So I'll work my way to 12. & see what sounds and feels optimal

OK thanks. Looks like I'll just have to test it between 5- 12 deg.
I've disconnected the egr, & will run 95' so i presume it'll run best around the 8.

Any actual answer appreciated, as I'm confused over the us chassie one.
But still helpful thanks

Is 12deg with advance still connected?

Out of a 1987 nissan navara. 4 spark plug.
I'm picking it's non us model as they didn't have navara. I'm sure the 720 pickup is different but i could be wrong.

Hi.
I have just rebuilt a 1987 z20 & would like to know what the exact timing should be.
In Google i find everything from 5deg to 12deg

Does anyone have a Haynes manual for correct info.

So the issue was:
1. Slightly high float level,
2. Choke wasn't fully coming off
3. Hot gas inlet from exhaust was staying active

So disconnected 2&3
Fixed the float lvl

wow you made me go look, always thought it was a smaller version.
Mainly used by the partner.
Apologies it is the 2.7
I shall correct that now

7 seats
auto
hi/lo ratio
2.7 turbo diesel
Has a small oil leak around rocker cover.
Any questions please ask
or contact 0212421044

But yes blue did adjust idle speed depending on the mixture.
I actually altered the stop screw first. Now that's a pig at even with air filter and housing off

No blue goes into the housing just in front of the throttle leaver, located at rear of the carb.

Stop screw sits on a white plastic (kind of hour glass shaped) piece, which is controlled by the auto choke located at the front.

Does that make sense?

Also have the white one in profile pic, 87' navara, 3.8 going into that.
This one is 1990

Also have a Mistral for sale, 2.7 turbo diesel, auto
Listed here

Could someone tell what the blue and green circled screws do exactly.
They are on the drivers side of the carb.
Picture 3, need to enlarge to see circles

And its an auto choke but that seems to be operating ok

Thanks,I found a stuffed spark plug earlier, running a lot better now, no sputtering etc. It does blow abit of white smoke Would the spark plug cause excess fuel consumption? Or do I need to look further??? I will post a pic here once I work out how, carbs have too many screws and adjustments for me ...

Hi all. I just bought another 1990 Nissan Navara na20. The previous owner had just had the carb rebuilt, butit was idling really high cold and warm, I have adjusted the idle, but here is the big issue..... it is using a tonne of fuel, and tends to lack power and will often stutter. I have made small ...

And I'm not sure. D22 i believe. The st-x.
The 440 is too expensive unfortunatly

Thanks I've been looking around.
Price may be pushing it. But working on getting them down more.

Also seen a 2014 Colorado. Very nice slightly used, but it's auto. I want manual and that's just a personal preference.

i was expecting that too

Im looking at buying a brand new 2014 Navara.

Does anyone have comments or info.
(& before anyone says anything i cant afford the 550)

Anything else appreciated

I have considered it. But it means sourcing or making new plates, mounts, drive couplings etc etc etc. And at this stage it should cost me f all......i really don't know what to do. I've delt with him for years without issue. ..... But I've been considering it for along time. Maybe just as viable to ...

haha
That's not helpful

Sibianmud. Not sure what hubs are worth, give me a price. a spare set wont go astray.

Sorry, have been extremely busy at work. Putting a 3.8 commy engine into my Navara. Had some issues at the start with the kit he purchased, nothing seemed to fit right. That was march 2012- nov 2012 which I was then told he has it sorted. Since then he has promised it would be done within a week or ...

Does anyone here know Paul Tulloch personally?
If so could you please help me to get my truck completed.
It has been with him almost two years and I keep getting the run around, I have herd promise after promise and I am yet to see any progress.

Any help would be great.

Still waiting on my 4wd to be completed.
Does anyone know Paul Tulloch extremely well!!!!!!!

hey man, im in wangas, need someone to go out with when i get my 4wd back, currently putting bigger engine in.
my mate i go out with just sold his 4wd, he's going to regret it once mines back lol

im in wanganui. got the commy motor last night so it is a go once i get everything needed. as for cooling system the radiator has been cleaned professionally with the tank off, t/stat tested. plus block cleaned out. therefore must be getting air in system. hose only collapses when overheating ...

Nice try. But radiator cap is new. New t/stat, new waterpump and fan, new hoses, clean radiator twice, acid washed block, checked timing. Bottom hose collapses under revs when overheating. Only other thing i havent tried is taking exhaust off to check if its partly blocked.

its petrol. z20 engine. rather gutless but was working well
