I believe this has been discussed before (April 2014) but I have a 73 150 super 2 port (non autolube) with stock internals and exhaust, and have a 20/20 carburetor I would like to use. A member by the user name of "Tierney" advised to use a 55/160 idle - 160 AC/BE3/102 main - 60 starter for the SI 20/20.
Any advice would be much appreciated.

then consider this:

and read this: Mixture screw adjustment, got a good link?

With a 20/20 it sounds like Tierney is in the right ballpark, look at the PX150 for
a comparable setup..
