Default Pros and Cons of filling the exhaust crossover?

Hello,

Mine is unfilled, and I use the hot air choke with success on my tri-power.

I do have an electric choke ready to go.

Many seem to block the opening with with a metal plate.

Others fill it with moltem aulminim.

I've heard one guy just wad aluminum foil in there, which of I found to be the most genius.

Do you do both sides?

Is is true performance or reliability gain and that it keeps the fuel cooler?

Does i have an advantange in warnming and atomizing the fuel?

Any info you have would be appreciated.

Thank you.
