'81 SAAB 99 GL
'74 motor
Zenith Stromberg 175 CD carb
I can't get the mixture right
damper is filled with 10W oil per SAAB manual
If I adjust the mixture to < 4.5% CO at idle, the mixture leans out on acceleration and the car runs horribly-hardly drivable. If I adjust the mixture so the car runs decently, the CO is up at 7% and the car idles horribly.
What is the problem here! I have a new needle and jet. Adjustable jet, fixed needle. I have not adjusted the float level. Could this have anything to do with my problem? Also, I recently installed an electric fuel pump and pressure regulator, but mixture adjustment problems predate these modifications.
