Just started a Z-S to SU conversion to dual HI4's on a 76B.
Mostly flying blind with some notes garnered from the list
and from Porter's rebuild book.
Of course I immediately came up with a question I hadn't thought or
What happens to the catalytic converter? Does it disappear? Is it removed
(Yes) and not replaced?
Isn't the catalytic converter a legal necessity?
In addition, if you have any wise and experienced comments about
possible trouble spots and their solutions, feel free to tell me
