Ladies and Gents,
Can someone point me in the right direction for Carb Jets. I don't need mains as I have quite a few of them, but I do need the smaller Air Corrector type jets. I'd prefer 100 and 110 sizes, but happy to take anything (as long as the head is intact).
Help appreciated.
Woz :D
I got a load sitting in my house, just need to find time to put them in shop, all different sizes though, didn't go as low as that though when purchasing
Would you be willing to sell me a few directly? I can PayPal funds.Quote:

Also interested, I'll buy a few too if available.
After this weekend they will be in club shop for all
Awesome, loads better than soldering and re-drilling the jets. :agree::)
Is there any update on the jets going into the club shop please?
Removing a bottom end from a clio and then if time will be on tonight
New shop group added for all carb parts, all added now ready to be ordered
No air corrector jets! :(
That's on my next order with them. And any other items or quantity needed. As delivery is expensive unless bulk buying from them.
Thanks for that Bigfoot but 1st stage/AC jets are what is needed.
What size air correctors would people want me to order in?
I don't need any but I would say for most applications a 0.9 and a 1mm would be the main sizes to go for. :agree:
id 2nd that tooQuote:

0.45mm idle jet.
0.40mm accelerator pump jet.
1.7mm needle valve.
Yeah, I think that would cover most applications, possibly a 1.1 mm size too. That said it's easier to drill to a bigger size than solder and redrill smaller. So unless others want a 1.1 too, the 0.9 and 1.0 mm should be fine.Quote:

Am I understanding it right that the main jet cannot be removed?
Currently I have:
1.3 main jet
1.3 second stage
0.7 first stage
1.0 or 0.9 AC jet (not sure)
I've be advised to get
1mm first stage
0.9 AC jet
Standard main
Does anyone know where I can get these please ?

I think it would be handy to provide 0.7, 08, 0.9 and 1mm.
Laurie,
As per FB page this is what I would do in your situation before going down the malpassi route.
Change your 1st stage to 1mm, check that your AC is 0.9 and change your main back to 1.2m. Make sure you have a decent fuel pump and you should find your afrs are fine up to 20psi.
If you still need fuel up 2nd stage to 1.4 and then fit adjustable fpr.
I think I have a couple of 1st stage/AC jets somewhere.
You can buy mains from RTOC shop now.

Agreed, Fordy sent be a batch too and very useful to drill yourself etc. Pretty certain he has none left now.

Re-jetted standard venturi I've just been told but the chap I bought the car from.
It should say 25mm on it then. Worth checking it hasn't been bored out.
Group A venturis were 27mm and stamped as such.
Check these articles if you haven't already. They make for great reading:

You would only need to increase the fuel pressure to the float chamber if it's emptying. You'd have to be making a lot of power before that was happening. Unless maybe you are spending a lot of time over 100MPH on full boost, sort of thing?
How much boost are you using?
