Name this part!!!

[c_donno2001]

Hi guys im hoping for a little help here with the name of a part and its function.

http://i102.photobucket.com/albums/m97/c_donno/IMAG0193.jpg

Its the part with the white marks on it.

The reason being that im after a little bit more fuel ecomony from my rb30 carby... Its a little hard on juice.

Ive recently serviced it, all fluids, oil, plugs and filters but havent noticed any increase in economy.

Then when I was poking around I noticed that the top pipe on this past in the pic above has snapped off. Someone has tried to do a bodge job on it and has filled it with glue :( so im after a new one. Im also wondering what it does and could it be affecting economy as its connected to the carb.....

Im also going to service the carb this weekend and Im going to use this kit (also hoping that this is the right kit for my carb)

or somthing similar any advice or anyone done this. Is it worth doing it???

Any tips would be great thanks :)

Hi mate, Im not very familiar with the RB30. Could it be something to do with an auto choke? Looks like it might get heat off that coolant pipe to work the auto choke on the carby?
Im just guessing and probably nowhere near the mark! Hopefully someone will be about soon to help ya out.

[c_donno2001]

I originally thought the same way you did.... something to do with the choke using the same trail of thought of the engine heating up and knocking out the revs, but I dont have an auto choke I have a manual little pull choke in the cabin..

Hmmmmm well ill revert to my second thought: I know nothing of the RB30! lol.... Hope you sort it out mate

[nissannewby]

is it a pull choke or hand throttle as the rb30 models had a hand throttle as well i think. i would also be incline to say its for your auto choke as its being fed from a coolant pipe.

[c_donno2001]

Im pretty sure its a pull choke.... but ill go through the manual and have another fiddle around tomorrow just to confirm!

How can it be a pull choke?

maby im using the wrong terminology but is a choke that is in the cabin that you have to pull manually not a pull choke?? tappa slappn about???

If you are talking about the little knob to the right of your steering column(on a GQ anyway) it is a hand throttle controller not a choke. and as far as the tappa slappn, I think that might be a iPhone/Smartphone expression.

[growler2058]

Mmmmmm me thinkum this is the start of the common debate about a hand throttle v choke v can I use it for cruise control (no no no not for cruise) Are we talkin about the knob rhs of the steering wheel? If so I'm 99.99999999999999% sure it's the hand throttle

A pull choke is part of the carby with a cable going into the dash that you pull. The part in the pic isn't a carby or attached to a carby. The pipes look like vacuum lines not a cable. The large pipe at the bottom of the pic looks like a coolant pipe. None of these things look like a manual (pull) choke.

Ps that is my tappa talk signature at the bottom:)

yeah he is using Tappa Talk app on his phone so it can be a little limiting when responding. Drives me nuts so i just use my browser on the phone and have no trouble but i am with Telstra ;)

I think he's talking about the part in the photo with the white marks on it

You might be better jumping on a Ricer forum for that as the RB30 is a popular engine to mod for Ricers and they'd likely know a bit about it.

Come back here though bud we no stuff;) just not that ;)

Unfortunately I don't have much in the way of Rb30 info in all the manuals here mate.

You could try the workshop manual on here. I know it has a little bit about them but not sure if it will help.

Where do the vacuum lines go? It looks like a thermal switch that only allows vacuum flow when the coolant has reached a certain temp. They used to use them for vacuum advance on distributors etc

Aha, I didn't think of vacuum advance.

looks like it's connected to the coolant system. it's not on any of my old vl commodores so not sure? heater hose return lines or something

Vls didn't come out with carbys did they? So that might narrow it down to a carby related part?

That is true the were efi. picture didn't look anywhere near the carby though. Not much help

Hey Growlers,

Open Debate - I own a diesel so no choke required(Glow plugs only) On my truck it is a HAND THROTTLE, not a cruise control(but it does work well at low speed to regulate speed)

Debate Closed



And we don't need any Mass Debates

[taslucas]

Did you have any luck donno? Could you post some more pics? maybe one of where the hoses go into the carb?

[Robo]

So what are the vac lines actually connected to ?.
It looks like a choke temp switch for automatic choke to me.
Remember 85 Carby XF Falcon had this same looking device and that's what it was.
I had to replace it, so I remember this, 20+ years..
F^*# I'm getting old.
Cheers

[c_donno2001]

I stand corrected here on my pull choke / hand throttle thingy. Im farily sure that youse guys are correct and that it is infact a hand throttle.... My bad sorry guys....

and the vacuum lines go into the back of the carby so what was being said about the temp cut off for an auto choke would make sence, coz this part is broke and there is no choke on cold start you have to rev a little to get her going.....

If youse want more photos of said vacuum lines and their origin / destination ill get better photos there tomorrow..... cheers guys.

[Robo]

Get hold of a manual, and see schematic for part description.

If you have a port you could connect too.
You may be able to test this, if choke then worked cold.
You can't leave it connected as choke would stay on without the switch.

If it were a MK patrol they had a manual pull choke, and a manual throttle setting cable also.
But shows my age again. lmao

The valve is a thermal vacuum valve orTVV it is a vacuum valve which controls the EGR or exhaust gas recirculation valve.
It helps with controlling the exhaust gas emissions. You may get an after market one from repco or supercheap other wise just block the hoses off

Good man that's the answer I'm after. Kinda makes sence coz the bang of petrol fumes would knock a galloping horse.

I wonder will it help the fuel thirstiness??
