Hi Adam,

 

Thank you for considering McMaster-Carr for your purchase.  However, we will not accept orders from your location due to the cost of complying with US export regulations.

That's a bummer.  If all you need is some set screws, I'll see what I have & could send you some in the mail.

[hiy_po]

I dont know if I can do it, but if possible I would buy some and send to your address or any US address and get you to forward to me. I would just need to know postage costs and if you want a fee just add it on and can send you a payment by what ever method works. 
This car is my daily driver and am out in the bush so I do need to get it going again asap.  It is really running to rich now to drive.
 If you do have half a doz 6-32 and maybe 4x 8-32 you have spare and could stick them in an envelope and send me I am at

It is absurd That I have been chasing these things for over a month and cant get them.
I have used the mounts from an old computer mother board (see pic) to do the LIAB, and made my MAB adjustable as well. but am out of them nowl. The original MAB look to be the same as the IDCR's so have soldered the bottom and drilled to 0.040. Just waiting on Cliff to give me a size to Take them to and I can get this thing at least good enough to drive.

       is there any chance I could get a spec sheet or a link to what the small cubic inch motor Quadrajets were setup like. I have searched but with the exception of a couple articles that dont go into detail I cant find any thing. It would ne extremely helpful to know what these factory carbs were set to. With my low compression I dont expect they will work perfect in mine but it would be great to have a base.
 I need to order a gasket set and some grub screws to.
 And what size should I have my IDCRs drilled to?
                                                                           Thanks.

I'll see what I have, I should have at least that many. We'll give it a try.

[hiy_po]

Wow I thought I finally had some until I added shipping
1 bag 25 screws
1 bag 30 screws
$US171
Good grief.

We ship overseas daily, typically about $18-24 to most places if the weight is less than 2 lbs.

I also stock screw in and drive in air bleeds....

[hiy_po]

OK so what do I do just go on the website and click away??
Will go look now. By the way I bought another Quaddy today but a pre emission one I think without the APT. Just got to wait for the post man to bring it.

[77cruiser]

Do you want the screws from me or do you want to see what Cliff can do for you?

[hiy_po]

I cant actually see them on his website???
I will grab a basic kit and screws if can find them but dont seem to be there.
If You still send me some let me know what you send and will buy them off Cliff to send to you to replace what you send. If that just isnt a logistic nite mare in the making.

[hiy_po]

I cant list my self as Australia it only gives me USA option

[77cruiser]

OK I'll get em out today 6/6-32 & 4/8-32.

[hiy_po]

Thanks heaps. If I cant get anything else at least I will have them.
If I cant get any any other way I will buy from them and send to you.

Is it seriously $US137 to ship two small bags of Brass set screws?

Hi Adam,

the freight is what it is. If you have a forwarder in the US, you can always ship the order there (free), maybe they will give you a better deal than $137 for this small amount of material.

Thanks

Let me know when or if you get the screws, PO said could take up to 2 weeks.

I sat down today and had a good think about how this carby works, I drew up a picture of the Idle system and had a good hard look at it. It I am now thinking the Lower Idle air bleed is actually bleeding off the vacuum from under carby that pulls the Idle mixture threw the Idle system. The bigger the bleed the more the Idle down channel restriction needs to be open to compensate for less vacuum which means more fuel being pulled threw for Idle. I want less not more. So reduced the Lower Idle air bleed from 2mm down to 1.65 mm, This one change increased the vacuum on the whole Idle circuit so reduced the Idle Down Channel restriction from 1.7m to 1.2mm to pass less fuel down to the Idle mixture screws and closed the Idle jet at the bottom of the Idle tube from 1.3 mm to about 0.8mm. The theory is that once it comes off Idle onto the main circuit the small jet will not allow alot of fuel to mix in with the main system which is a more efficient fuel supply. The main system is better at emulsifying the mixture than the Idle system so I want that to be supplying the fuel not the Idle system.
On start up it idled well. Idle mixture screws are only out about 1/2 a turn out from fully seated and throttle stop screw is about 1 turn open, which suggests it is still pulling plenty of fuel from the Idle circuit. Got it to Idle as low as 600rpm but was a bit rough and was happy at around 800rpm. but was still showing rich. I want the Idle to go lean of stoich so thinking I can still go smaller just keep all three settings even untill the Idle mixture screws need to come out more than 3 turns, that would suggest The fuel coming threw the Idle circuit is getting low.
 Quick drive down the road and back and transition seems good, no stumbles or spit backs but cruise is still rich so that is also suggesting I am still getting an excess of fuel from the Idle circuit mixing with my mains. Be interesting to see how far I can reduce it and if I see the mains go leaner as I do..

Thanks Cliff for your advice on the Lower Idle Air Bleed being a leak and they are setup smaller for a reason. I think I am getting alot closer now.
