Mark I wasn't talking bout the gap between the top and bottom cowl halves
but rather the fact that the cowling inlets are smaller than the mating
mouths of the plenum chambers. With the plenum chamber mouths going over
the cowling inlet mouths and having a gap between the two the incoming air
will probably draw warm air from inside the cowling in with it. I used a
seal made from a strip of a car's inner tube glued to the circumference of
the plenum chamber mouth. Once the cowling is on I use my finger to work the
tubing over the outside of the cowling inlet. Perfect seal.
