Banjo, I thought only the KE55 Borg Warners came with 9" drums?

So I sent RainWarriorDregs a PM & he is yet to read it. Not complaining, he probably has his own life to live. Can anyone else please shed some light on this illusive RB alternator conversion?

Alternator

What happens to the reds when you turn to Start? Do they dim & if so, how much? Does the starter motor do anything at all, even just a click?

When you say battery drained, you mean no reds at all? Some of this might suggest ignition barrel switch, given the varied symptoms you are describing.

Thanks man, PM sent :D

Thanks RainWarriorDregs, but Google is not helping me. More info please? :)

I've never seen a 2 door KE70 in person! Did these ever get sold in AU?

Thanks heaps Banjo, looking forward to it! :D

Hi peoples, The interwebs & my crappy googling skills have turned up retrofitting VL Commodore alternator guts into a 4K one, but no direct replacement options. Can someone please let me know what 80A or higher alternator is a direct swap? I don't mind having to modify plugs, wiring, etc :)

Well, well...so it WAS the EGR valve after all! Pulled it off & bunged the manifold with a suitable sump plug on the weekend & drove it today. Idle & off-idle hesitation issues GONE!

This may help you man: http://www.redlineweber.com/html/Tech/carburetor_set_up_and_lean_best_.htm

Definitely not vacuum in the tank. This was the first thing I checked. Vented cap...leaks like a sieve on hard corners ;) Okay, pulling the pick-up out tomorrow! (Weather & hangover not withstanding, LOL)

Put electric pump in the boot today. Electric pump pushing to the stock mechanical = slight improvement, wherein in doesn't lean out quite as much, but still does. Electric pump only = identical symptoms to mechanical only. Electric pump gets considerably noisier during the lean events. Maybe the tank is full of crud, which blocks the pick-up sock when sloshed around, but drops out of suspension after sitting for a while?

Nope, tank outlet at top...Red won't like that!

Found the Holley. What do you think? Never had this problem with sidedraught Webers...ever!

Nope... :(

Needle eventually seated after running down gears & bowl filling...oops...not enough posts to edit...

Your symptoms sound identical to mine! Only thing is, I'd have thought that running down in gear from high revs with the needle seated would result in a full bowl at stop, especially with the mechanical pump...but maybe not... Thanks for the idea, will try it out next weekend & deal with the hassle until then. Today I almost managed to find a decent middle ground between idle types, but not quite there & it wouldn't be actually fixed anyway. If your suggested test setup works, then all will be good. Have a Holley Red in the garage somewhere :)

Okay, so now this is driving me mad! Same symptoms as before, idles great when warm, but drive for a while & idle is shit, plus stalling a off-idle hesitation. No fuel dribble now, no matter what setting the FPR is on, even at highest setting. Ready for this? Put the LM1 sniffer in her today & stalling is caused by a stupidly lean idle mixture, that only occurs after driving for a while. After idling badly for some time just sitting idling, the mixture gradually richens. Let her sit for a few minutes & idle is very rich. Driving & pull to a stop: Around 40/1 Idle from start: Anywhere from 12-18/1 Blocked something, but WTF & HTF?! Please help...I've never experienced anything like this before :(

Good point :)

Of that, I couldn't be sure. It was just dripping from the inner edge of the venturi. If it does happen again today I'll look more closely.

Thanks for the replies :) The ProFuel branded regulator ended up having a broken diaphragm, so it wasn't actually doing anything. However I'm still at a loss as to why the inline restrictor didn't help. Either way, installed a new regulator today & she's behaving quite a bit better! After a few pure idling & driving then sessions today, the throttle plates are dry at idle :D Bit of idle speed variation however...heat as suggested by altezzaclub perhaps? Pretty happy now, but the drive to & from work tomorrow will be the decider!

Hi people, Have a 32/36 on my 4K that for the most part works okay...BUT.... It will idle fine, but after driving for a few minutes idles fast then eventually stalls. I have figured out that this is due to fuel dribbling out of the venturi at idle...but only after it has been driven. It only happens after a few minutes of driving. If you start the car & let it idle (hot or cold), it will do so forever, with no venturi dribbling unless you then take it for a spin. Tried both Repco low pressure electronic fuel pump & brand new standard spec Nikki mechanical fuel pump. New fuel lines. New fuel filter. NEW CARBY! Checked needle & seat, looking good. Removed & checked jets/tubes, no cleaning required, just like new also. Checked float level & adjusted for 1mm variation from spec. Put a restrictor inline with the hose from pump to carby with a bloody tiny hole in it...no difference. Pro Fuel pressure regulator also yields no result, except the the bowl runs dry when you give it to the car up a very long & very steep hill. Checked for vaccum leaks, none found. I'm now thinking EGR valve. Since the vacuum line to the valve isn't connect to a vacuum source, I expect it to be doing absolutely nothing all day long. However, does anyone think it possible that maybe it opens up/leaks when exposed to the higher temperatures of loaded engine operation but may otherwise stay sealed if only seeing idle temp exhaust gasses? Other than this possibility, I can't for the life of me figure out why the carb is doing this & it's driving me insane! Please help...
