On the manifold mounting flange at the rear end,  what is the slotted area
for?  Also you didn't answer my question previously that being, what

happens

to the disused side ports, are they just covered up by the mounting flange
or do you propose to fill them?

Tony Beaton

I don't follow you. There is no mounting flange.
First I assume you are talking about the P-port engine.
all disused side ports are filled with high temp epoxy. JP Weld can be

used

if you first heat the containers in boiling water to thin it out and then

mix it.

If it is the slot in the slide throttle then that is to accommodate the
throttle clevis that connects with the push pull rod going to the

instrument

panel. Here are a few pics & 3D illustrations that hopefully will clear

things

up.

   Correct. There is recent evidence from Dave Leonard that it is
   absolutely essential to contain the inevitable standing wave fuel mist.

Paul,
I would have thought this was a obvious necessity. If the fuel fog is
not contained you will have the mixture sag lean on you. On engines as
old as 40HP VW's there was a need to contain the fuel fog. There was a 6
in long tube in the old oil bath air cleaners for this purpose. When we
inject somewhat downwind from the port opening it wouldn't be a problem.
If your injectors are within 6" of the port opening though I would be
concerned. It would be one of the problems faced by the into the
bellmouth "showerhead" type injectors for sure.
