I don't think the slots are nessesary, but the tunnel is pulling air OUT in
normal cruise, not in. In the stall you get a little in but I have never
smelled exauest in it. I also put the seaplane grommet in the throttle box.
looks like it will work. I also shortened my throttle cables and went to a
mower repair or bycycle shop and had new ends installed. (dont remember
wich) works fine.

I would expect these to have the opposite effect - under the
fuselage/wings is
an area of high pressure, which would reverse the air flow. I believe
some
posters to this list have mentioned that air forced up into the tunnel
comes into the cockpit through the slots cut for the landing gear and/or
throttle. In some cases pilots have reported exhaust smell when flying
at higher angles of attack.
