KR> Latest intake manifold experiment

[John C Edwards]

Yes icing,or condensation can and will manifest itself downstream in the 
intake manifold.  The  "T" in the intake manifold of updraft/sidedraft 
manifolds creates a high pressure area where the air/fuel mixture 
accelerates and bends as it goes around the corner and up into the two 
intake runners up to the heads like on a VW or Corvair. At that point, 
the temperature drops, and condensation or icing occurs depending on how 
close to the exhaust is the the intake manifold and what the undercowl 
temperature is at that point. Pull the lower cowling off your aircraft 
if you dont believe me on hot summer day and look at the area just aft 
of the carb where it enters the "T" of your intake manifold and you will 
see the condensation form on the outside at the very least.

KR> Latest intake manifold experiment

[samantha toner]

Icing occurs on the throttle flag due to the depression of air as it exists  
the venturi.It wont manifest itself downstream in the manifold as the pressure 
has equilised

A concern that I have about that is icing.  I think that with all those very
small wires, it would be easy for it to ice over.

In my younger days we used to put aluminum window screening sandwiched
between 2 carburetor spacers to help atomize fuel.

KR> Latest intake manifold experiment

We used to do this same trick with our old Chevy dump trucks so they had
enough power to get in and out of the silage pits to dump the silage. Don't
know how much power we gained on the old 6 cylinder engines but it was
enough to do the job. la...@lebanair.com

In my younger days we used to put aluminum window screening sandwiched
between 2 carburetor spacers to help atomize fuel. Theory was that the
screen creates micro vortexes and helps with a more even air/fuel mixture
distribution to all cylinders. We didn't have a dino machine to test this
out, but my guess would be that we gained at least 5hp. 
This might be worth looking into for the uneven burn problems.

We did the same, but sandwiched in between the screen's, was one of Mom's 
Kotex's and we then called it anAir Filter  :-)

I have an old 1835 Hapi engine and was having problems with uneven fuel 
distribution to different cylinders as indicated by hot and cold egt 
readings. I made a scaled down Cyclone Vortec generator of my own since 
the one theirs(Cyclone Vortec) was too big to fit in my VW intake 
manifold. It evened out the egt readings and cured the sometimes 
sputtering problem that i had,, if the mixture wasn't set just right. I 
can now run a leaner(as set by my air/fuel ratio gauge) and cooler egt's 
than before without the cyclone device. My kr-1 is now much happier with 
my Hapi engine!

Yes, if you have a carb with a choke on it, I would not use a primer either. I 
have an Ellison and therefore must have a primer, or it won't start.

I removed my primer as I was only using the choke to start. I found that I was 
flooding the situation with the primer. I found gas dripping from the carb 
intake when another "ramp rat" pointed it out. This on a HAPI 1835 with the GP 
carb.

Well, my latest folly with intake manifolds failed miserably.  It started 
quite easily, but refused to increase power past 2000 RPM.  So, I'll chuck 
that wad of cash in the trash and try something else.  But, I did find out 
that you can start your VW engine quite easily with the primer going to only 
one of the intakes at the head.  So, I would assume that the same would be 
true for the Corvair.

Dan
I only have One choke on  carby on the type 4, starts easy.

Sure that is not a mixture problem and not the manifolds?
