1970 911T Zenith 40 TIN

[924CarreraGTP]

I’m looking for a good tuning procedure for these Zenith 40 TIN carburetors in my 1970 911 T 2.2.. There was a Gary Suggate link concerning tuning these carbs but the link is dead.
Anyone have any tuning information to share here?

Just tested the link to the suggate UK website and was working for me:

Zenith Carburettor Manual

There are some really good threads here on tuning and jetting Zenith carbs so be sure to use Google to search the forum and not the built in search here.

Also, I highly recommend reading and understanding tuning for Weber Carbs as there is more info available and much of the same info applies.

A carb sync tool is a must as well.
