- Skids72 - yes it does have vacuum advance. and as far as a lean mixture? im not trying to say ur wrong, but a 600 cfm carb on a 283 shouldnt be lean AT ALL throughout any rpm should it?? if so i guess i could start looking into that problem some more. next week i will have installed that bigger accel. squirter. and i will let you know how that works. and i will definitely read up on those links which are much appreciated!! thank you!
