You really need a timing indicator and a TDC mark on the pulley.

You may not know exactly what advance curve is in the distributor you are using so you should set the timing not at idle but running.

I like to set timing at 30 deg BTDC @ 2000 engine RPM. You also need to check to see if the advance does not go much above 32 deg as engine speed increases over 2000 RPM.

In my opinion, it is always a good idea with mechanical advance to set to set the timing at 2000 RPM and not at idle.

Most FSI distributors have way too much mechanical advance.

The original Model B distributors, which work well in a Model A, only had about 12-14 Deg of Mechanical advance. You set initinal timing at apx 16-18 deg which gave you 30 deg at 2000 which is what you want.

Again this is just my opinion and others may have a different opinion.
