Most of the time I have to pull over and wait a few minutes then fire back up. I do have a wideband, but it is digital and not sure how accurate. (question, i had to install a switch on my wideband guage to go back and forth from each rotor because I am using 2 0xy sensors. has anyone solved that problem?)
here are my jetting settings:
Weber 48 IDA on a 13b street port. (4 port)
250 MAIN ( I know this is big, but my problem is at lower RPMs. Ordered a 190 and 220)
70 Idle
50 Pump Jet
F-11 emulsion tubes
160 Air Corrector Jet

Please help if you can! Thanks


Ok, so I got some new jets. I just swapped in a 60 idle and 220 mains. And now my problem seems worse. And my wideband is reading richer than before at idle. The choppyness is worse too. How can it be richer with smaller jets? AARRGGHHH!!
