Thanks Mark and others for the info on carbs. I talked with Ellison as
well today and they said it was a bolt on and forget it. They also
stated that the carb seems to be more efficient then the others which I
had listed.
Some of the other manufactures you have to change crap on the carb for
Keep it simple. As long as you factor in the permeability of balloon latex.
You'd have to subtract the permeability losses over time to calculate the scope
of a leak. I dont have the permeability of latex to air molecules (if you arent
using another gas with larger molecules), but you should
So, I'm finally getting started on my airplane I bought while I was
deployed. I conned a friend to help me by giving him the completed frame of
my Super Koala (his father is one of those who wanted a low and slow
aircraft). Tomorrow we are going to break ground on some of the projects I
have

I have an Ellison EFS-3A on my Corvair, with a primer in each
My Zenith has a choke. No need for a primer. The 2180 VW starts
immediately in any ambient temperature. There is no drama for hot engine
starts; with the 0-degree advance electronic ignition at zero RPM and with
choke off, starts are immediate. Max advance on the ignition is 29 degrees.

Ellison's are compatible with ethanol as well, although their website
says they're not. I suspect there's either some CYA there, or they were
thinking

If you noticed in my picture you saw a thread wrapped around the balloon and if
thread ?falls off that means the balloon has qshrunk which means you have an
air leak. Why make it difficult? ?Keep it simple

Yes you use a regulator on the air line or use a hand pump or be quick
on the disconnect.
Your air compressor may have 150 lbs in the tank but you can still
manage to fill a tire with 35. You would only need 2 lbs air to test the
tank and if your in a hurry to do a bunch you could put the tank
One thing I didn't see mentioned here is to use extremely LOW pressure. One to
two pounds through a regulator. Don't think you will be fast enough to just
shoot a little in there. Otherwise your square tank will become streamlined. As
usual don't ask how I know this.

Paradise,
VERY minimal psi I would imagine!

I think your Ellison EFS-3A is the gold standard. No float bowls, no
adjustments ever needed beyond initial set up. Carb ice resistant.
Aerobatic. The "mist bar" method of introducing fuel into the induction
system contributes to an even distribution of fuel to the cylinders. I
assume the
Rotec has upgraded their TBI to the Mark 4. The diaphragm is now attached to
the unit and upgrades all around. I bought the Rotec because of space issues
and Elison has stopped production. I had it available at the gathering for
folks to look at I hope to have it installed and running soon.
Be aware the balloon will expand and contract with any change in tank
temperature. Take your measurements when the temperature is the same on 2
consecutive days.
