Weber 48 IDA on lighlty ported (4-port, early 13b). Can't figure this out. had 250 mains and 70 idle jets. The car ran pretty good except for cruising. It would sputter alot. And on deceleration, it seemed to "load up" cuz coming out of deceleration and stepping on the throttle, it would just die out....much like the in the video. Got advice that my mains were too big, so I swapped them for 220 mains. Now it's worse and I can't even drive it. Also swapped in 60 idle jets. Please watch the video and see what you think. Thanks for any help!
