Hi Ricardo,
I would like to help with yor Saito gas engine air intake but as you saw in the blog posts, this depends on the type of engine, carburator intake, actual mounting of the engine and cowl arrangement.
What is the Saito model # and the type of cowl (like for a radial engine or more like an inline engine cowl) and is the engine inverted, upright or on its side? What type od motor mount are you using?
Do you have pics of your installation?
Cordially,
