34 adm car install questions

Post by fonz »

hey guys im going to be attempting the carb swap on the astron 2 2.6 in about a week got a carbie and adapter plate lined up.

just wanting to know if there is a write up on how to install? tips and tricks?

and is there different versions of the 34 adm off a 4.1 ford crossflow engine? or are they all the same?

thanks guys did a search but couldnt find much, but i could be blind and missed something.

also i know it wont make a huge difference in power, but im sure it will help when i hang the t3 off the side of it :D

Hey mate,

From what i can remember........
-plug the water gallery that comes up through the manifold (grub screw for example) & of course block off the other end which goes to manifold from the choke.
-modify the old cable linkage to the weber shaft.

Thats all i can think off at the moment... was a while ago now.

Also, you may find on the astron 2 manifolds, you may have to file a small notch at the end of the adaptor to clear the crank case breather inbetween the 2nd and 3rd runners; you'll see lol.

oh... and you will need to sort out an air cleaner, you can get the chrome carby top ones for like $40.

Hope that is some help, any Q's just ask.

Nick.

34ADM modification is a very rewarding modification.
You should look for a leaded carby from an XD or XE. XF Falcons are unleaded and are easily identifiable by the peculation tube rising up out of an above the carby.

Been there and done that. 34ADM seems to be the mod you do before you do fuel injection.
Fortunately I did a write up about the mod before I injected my engine..

Maybe a little ambitious.
There is a fair bit to do in manufacturing brackets, die grinding, etc.

I would recommend purchasing an additional inlet manifold and air cleaner from the wrecker before you start.
While you are at it, a can of carby clean and a complete rebuild kit for the 34ADM.

All of the hard work can be done on the workbench, so if you get another manifold, you can build it all together, then after work one night, you can just unbolt one intake setup and bolt the other on.

Here is a quick list of things to do.

-REBUILD the carby, strip the carby and stick all the parts into a tin, empty a can of carby clean over it all and let it sit for a day.
-Use a complete rebuild kit. There are two kits available, one only has gaskets in it, the other also includes diaphragms. Get the one with the diaphragms.
Here is the info you need on rebuilding the 34ADM http://www.l200ute.com/download/weber34adm.pdf

-Get an adaptor plate kit. The speedy kit bolts aren't long enough and you will have to get longer bolts,

-Grind out the two throats from the manifold to match the adaptor plate.

-Weld a thottle pulley from a Sigma onto the 34ADM

- Make a bracket to hold the throttle cable to the manifold.

-Modify a stock Mitsubishi Air-cleaner housing to suit the 34ADM. (Nothing screams a modified engine to a cop than a chrome after market sports air filter)

- Solder the yellow wires together from the electric choke and fuel cut solenoid to another piece of wire, this then connects to the wire from the loom that powers the fuel cut solenoid on the original carby.

When all of this is done, then you can think about swapping it all over.
After the new setup is in place, take the secondary jet out of the old minuki carby and fit it into the 34ADM.

Turn the key and see if it starts.

Hopefully you can see now what is involve and you wont attempt this all in one night.

I'm not trying to tell you what to do, I just prefer not to see you walking for a week while your car is off the road.

thanks jamie looks like u know what u are doing and talking about!!

not a lot of people like u on these types of forums these days.

i have been thinking alot about the carbie option but i think i have decided im not going to touch this engine at all, but have spoken to a mate of mine (a mechanic/engineer ) and he said he wants to attempt to fit either a 253 v8 in it or 1jz twin turbo :lol: although there is alot of other work involved with the two of them he said he doesnt mind fabricating stuff for it, so we will see what he is up for and if not ill just live with the shit power untill i buy another car lol!!

I am in the process of fitting a 34adm and can't work out the fuel lines... The fuel inlet is the brass fitting that angles down, to the left of that there is another fitting about the same size which is the idle nudger, but the one I can't work out is between these two and slightly above them both... Most photos of the 34adm show those fitting blocked off or non existent but mine has one in this position and I'm not sure what it's for... Fuel return possibly? But in found a post on wikipedia with photot which shows the fuel return to the right of the inlet and this fitting of mine is to the left, any suggestions?

I appologise that I'm replying to a 3 year old thread, I did come across a similar thread in the archived forums that was 6 years old (Did you know you can still register on the archived forums? I didn't realise it was archived so I registered and tried to reply then I found out, lol).

Jamie,
I've done my conversion, but I haven't driven the ute yet. My 34ADM is running the jets that came with it, 160 for primary and 180 for secondary. You say to take the secondary jet from the old carby and fit it into the 34ADM, is that to replace the primary jet in the 34ADM.
Is my 180 fine for the secondary in mine or too big?
Also, my 34ADM doesn't have a fuel return line, is this fine?
Cheers for the info mate, it's the best I've found on the net so far.
Regards,
Chris.
