Weber 44 IDF mixture help needed Options

[tornik550]

I am working on getting my idle jets correct. My mains seem ok.

At idle (800 rpm) I am getting a reasonable air fuel ratio (14.8 using innovate a/f gauge). I'm using 50 size idles. If I slightly press and hold the peddle to a steady 1200 to 2000 rpm the a/f goes to 19. The car drives like crap until I reach 2000 rpm when the main jets kick in- at the same time the a/f ratio goes to 14 or so.

What adjustments can I make that will leave idle at the same mixture however rich up the mixture til about 2000 rpms? I thought that was mainly idle just only?

I did try to increase the idle jet size to 55. The idle mixture goes down to 11.8 at 800rpm and is perfect between 1200 to 2000 rpm. Confused- I can either get the idle correct OR the low rpms?

I have followed weber's info on best lean each time I switched jets.

Ideas? What am I missing- i'm sure its something simple.

it sounds like your close. does the car sputter and fart thru the WHOLE progressive circuit or close to the end. an easy way to tell is to pull your main stacks and drive it. not a few blocks but for a few hours. this will give you the best understanding about how the progression circuit works. your on the right track.

what distributor are you using? what size engine? big cam? accelerator pump connected?
