The 'E' Type Forum

Hello.
I am an owner of 1972 V12. Lately it seemed to be off so I decided to adjust and balance the carbs. I have four Zenith-Stromberg units. I was sure I followed the instructions from Repair Operation Manual closely, but after making the adjustments, the car is running worse. It is now super noisy, almost like a diesel. During the adjustments, I saw that I couldn't get the sound of one of the carbs like the others, so I just got it as close as possible.
Has anyone out there had a similar problem, and the solution? Did I over-performed?

Hi there, I'm no expert on tunimg or setting carbs but the usual advice is to check timing etc. before the carbs. That said are you able to get back to your original settings? I'm sure one of the forum experts will be along with a bit of guidance in due course.
