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. |
