I'm using Bruce Turrentine's DVD to overhaul a 20B. On the rear of the
engine there is a counter weight under the flywheel that didn't appear on
the 13B in Bruce's video. Anyone familiar with this and know how to remove
this counter weight?

I think you mean the flex plate for the auto transmission.
The 20B is very similar to the 3rd gen RX7 engines. 1993 to
2003.

For that you will need a gear puller and a way of locking the E-shaft
with a special plate.
