That shaft is for the air con. It increases the idle by pushing on the throttle linkages so the car doesn't stall.
When the throttle is opened the linkages turn away from the rod. It is impossible for that rod to stop the car from revving over a certain amount so I don't know where you get your "clues" from. Maybe the same mechanic that charges you $200 extra to rebuild a carby that was run on gas.

I think the aircon switch thing must work different on an rb30, as that's where I got that info from. I've been told that they are the same in regards to that switch but your completely right, the main throttle shaft turns away from the aircon switch on a TB42.
It's not a single mechanic I talked to about the rebuild cost, it's the franchise procarb. Maybe others do it for a different price.
Tap, crackle, pop
I had another look at my mates rb30 carby last night. The shaft that i pictured above (which is the aircond idle switch on a TB42) looks the same as on an rb30 carby but on the rb30 carby it is for the auto choke. The accelerator still turns away from the shaft but if the shaft doesnt moved freely then the choke is stuck on and that is why the engine wont rev out.
Just thought id clear that up
The denting of the float is a known occurance. It may not look like it could be a common problem but quite a few carby specialists agree that it happens.

Good luck with the rebuild kit Matt. Let me know how it goes.

Done the rebuild today, still won't idle very well. Seems like the coil or dizzy is playing up to me as the tacho is a bit jumpy as if it's losing signal or something.

Does it have point's or pertronix ? if points it may be the condensor and points just replace them with a pertronix anyway money sell spent.
Try disconnecting the noise suppressor.
Check for any bad connections at the coil and resistor.

Probably a stupid question but what is a noise suppressor and where is it? In the rebuild kit there was two little ball bearings, both were different sizes. I couldn't find where they went so I didn't replace them. Any ideas? All of the bits I pulled out appeared to be in good condition apart from one gasket on the sandwich plate between the top and bottom half of the carby, it was split in the middle. Had a couple of blocked holes on the main jet and a couple of paths were a little slow flowing. Apart from that everything "looked" to be in near new condition, but I replaced everything anyway.

looks a little like a condensor near your coil usually i think lol it's been a while.

ImageUploadedByTapatalk1346568337.014533.jpgYeah it has points.
Drove about 130kms in it today to get some bits and on the way home it was ticking like a diesel when at full throttle going up hills and was getting quite hot, about 3/4 way up on the temp gauge and normal is usually under 1/4. The only thing I have done today was take off the dizzy cap and rotor button. I thought the heat could be from running a bit lean so I turned the "Rich/Lean" adjuster thing on the carby to more on the rich side of things to see if that would help but it didn't help. I had normal oil pressure all day. Could have I stuffed the timing when I had the dissy cap off?

Might be A bit late to reply to this but if you haven't done anything more I would check some things before spending the money on getting the carby rebuilt. The best bet would be to get hold of a second hand carby that has never been run on gas and rebuild it. I had the exact same thing on my old patrol. It would run on petrol but not idle. I had a kit through the carb and it made no difference. Because the gas runs dry it can wear down the throttle shaft that runs through the carby which allows it to suck through air and stops it drawing up fuel for idle. A good way to check if this is the problem is squirt oil all around where the shaft goes through the carby and if you can cover it all it will idle for a few seconds until it sucks the oil through.

The noise suppressor is attached to the front of the dizzy down the bottom. The thing on the coil is a resister. Pertronix is definatly worth doing regardless and very easy to install. No you can't effect the timing by taking off dizzy cap. Also is that a gt40 or gt40R coil?
