AFR numbers for Weber

[Son of Marty]

The idle jet holder on the dcoe's has no metering function it just holds the jet.

Got it. Thanks Marty.
But I do see Pegasus sells different holders. F8 and F9. ? 
Even so, looking at the DCOE diagram, I find it hard to see how the holder would make any difference.
I guess just wishful thinking on my part.

[Son of Marty]

The f8 &f9 on idle jets refers to the air bleed size of the jet and the whole number is the fuel inlet size.

[Moto Carlo]

Sorry can't quite get my head around it.  
More air with the f9?
So the more air would indeed make the idle jet side of things more 'tune-able" .

This is the hole that meters the air in the idle jet it works like a tiny emulsion tube and the air through this hole is mixed with the gas before it's passed into the engine. For some reason the idle jets like the emulsion tubes follow no known numbering system so a f8 and a f9 could be on opposite side of the rich lean chart instead of the next logical step.

Reminds me I need to spend more time (and unfortunately more money) on those pricy little brass bits to try out some different arrangements. Eurocarb must love me... sigh. 

 

 

 

I have found good jet prices from this guy: https://www.ebay.com/str/carbdeal Shipping can be a bit slow as I think it's coming from Czech Republic but Weber jets always look good and prices are right.

.... Last problem I'm tackling is my linkage which is IE early cable which is not very smooth or responsive so just ordered different style to smooth that out and I should be done.  ....

 

What style did you end up trying?

All with that dangling carrot of , "When you get it right it will work great for years without any effort."

 

No no, I pretty much promise you you'll get it right, then second guess yourself days, weeks, or months down the line and screw it all up again in the name of science. haha.

He will also put together custom auctions for you if you have an assortment of pieces, including ones he doesn't have listings for.  I have ordered from him just a couple of times.....

I've ordered from his as well, very successfully.

And I am currently waiting from order on some Weber linkage from CarbDeal

Shipping to Canada is $35,  seems kinda steep.
