Dave,
Would you be kind enough to show a couple pictures of this arrangement? I am in the process of making up something for the spitty i'm building and could use the visual assistance. cheers!

I'm planning on using a Moki 1.8 in mine with an Air Hobbies muffler/mount combo. I am debating the exiting exhaust and cooling and will proably do it per the Brian Taylor plans, but would like to see how you handled this. thanks!
