I posted this in another thread but now its worthy of its own.
The kombi was running on and skipping a bit so I took it for a service. My normal mechanic was still on holidays so I took it to another trusted mechanic who gave it a half service but advised I get the carbi's checked/overhauled.
On the advice of the carbi shop I agreed to a $400 twin carbi overhaul.
Since then I have had problems.
Loads of stalling, lots of flooding etc
The most recent is it starts fine, autochoke comes on, I can drive it and it will idle in gear ok (its an auto) but when I tak eit for a run on the freeway it will stall when I slow down and wait at lights. It will not start for 10-15 miinutes and then its fine again
Any suggestions?
Please call if its easier and I will call you back

Its urgent because I dont want to waste anymore money on this that dont fix the problem

What no one has ANY ideas?

Only just woke up sorry. I sleep untill 1 on a Sunday. No kids you see

I say this quite often, and I will say it again. Check the distributor as I went down this same path on out twin carb 1800. I got the carbies done at a cost of $340 a few years ago, and not long after it was stalling before that the idle was high and low, not consistent. I was reccommended to get the carbies done by a mechanic also. They may have needed doing anyway, but they were not the main problem.

In the end it was a worn baseplate in the distrubutor. It was allowing the points to behave in an inconsistent way and when the dizzy got hot it would close up the points gap, and not start for a while.

It would be worth checking the settings on the auto chokes too.

Thanks HellBus
Thats sounds like we have identical problems
I will let the Carbi mechanic know tomorrow about the baseplate in the distributor.
I feel like I have been ripped off fairly significantly by this guy/shop but what can I do he still has to work on the engine as it is worse now than when I took it to him...

ps I have a 1.5 year old son so I was up at 05.15

Could it be something to do with the coil?

Not very likely, but if you have another 12v Bosch coil around, even one from an old Holden, you can try it and see the difference. It is not worth buying a new one just to find out. It will only take a few minutes to get hold of one that works and swap it for a while.

I eliminated any carby, distributor or idling problems when I went Subaru engine

^^ cheers

Carby mechanic says he has checked the electrics (distirbutor, leads, base-plate, coil etc) and he says all of it checks out.
So must be something he did with the carby overhaul.....idiot

Wont post the name of his business here yet but I am very very tempted

Yep once dizzy, coil, leads all check out, there is only really air leaks and carbys left. He may have bumped a rubber elbow on the manifold balance tube and it may have cracked or popped off. Quite common for old rubbers as they get brittle.

Try removing the spark plug leads one at a time with the engine running. If one cylinder is to blame removing its lead will make no difference to the idle. You then need to isolate why it's not working! My suspicion is that it is running too lean because of a vacuum leak. When the choke's on the mixture is rich enough to run ok. When it's off it's too lean to fire properly.

I know when he hooks up the air lilfter to the carbs it drops its idle rate quite considerably....
Every now and again (before this debarcle) if the Kombi back fired it was common for a 'vacuum tube' thingy to be blown off. It was easy for me to diagnose because it would always start but not idle

got it back from the carb guy today...he is bamboozled and cant fix the problem.
drove it home and it hasnt stalled yet so he may have fixed it by replacing dizzy leads
he mentioned tapets and because its an auto they may be loosened and that the stalling problem...any ideas?

Does it really cost that much to get the carbies overhauled? What do they do to them for that price?
I think I will go with plan B and fit a dual throat carby from something else rather than pay that to fix my ailing carbs

Well, if it's the tappets, it would take your mechanic 30min maximum to adjust them.

True enough, old Bosch coils are pretty universal. I usually end up shoving a bosch GT40 in things. Usually to help out with a badly worn electrical system. I know, naughty me.

Sounds like he badly botched the carb overhaul though. The dual carbs are tempramental to get running properly, however they are very simple too and it's hard to make a major mistake.

I had a vacuum leak once on the brake booster vacuum line. That took me a while to find.

I realise that you said that a vacuum line comes off when it backfires. It shouldn't backfire in the first place though. There's something else at work here.

azz you icu nurses are all the same, ventilate and sedate!
