Okay, after much searching, I found the link to the hoop thingy.
http://wingsforum.com/viewtopic.php?t=174
I dont know where the wings forum is, but all info is there except, what is the
metal used? From the pictures it could be Al. Steel or Stainless?
I have PM ed to Planecrazzzy, but so far no reply.
Has any one else built and use one of these?
Thanks,

The Ivo spacer does have a centering boss on the prop side, and a hole cut in it
for the drive flange boss, and both of them are snug fits.

Ok, we are taking about 2 different spacers. The Ivo spacer I was referring
to was just a piece of heavy wall tubing with 6 holes drilled thru in the
axial direction for the prop bolts. Everything hung on the prop bolts
themselves.

Ernest,
It takes fuel, air, and a source of ignition,probably outside of the combus
tion chamber.Something hot enough in the exhaust to set off the charge,too
much air with fuel in it,or too low of an octane .Look for any leaks in the
exhaust close to the heads.

There are two distinct and opposing conditions that could cause your engine
to backfire. Too rich an idle mixture letting unburned fuel slip by the va
lves into an exhaust system already heated by high EGT's when the power is
pulled back on approach. Or the mixture is too lean and it's on the verge o
f running on after the ignition is shut off.(my Harley used to do this on w
arm up when I pulled the choke off too early).
What is your idle RPM before the stabilization run? Is it different after t
he stabilization run?
If your heart can stand the strain, let it backfire one last time and immed
iately look at the plugs. Do the same after a stabilization run and note if
there's any difference.

Hello all,
I did a search in the forum with "backfire", "back-fire", and "back fire" w
ith no results, So here goes....
I have an 80 hp 912 UL on a Zenith 701. When I return to my hangar after f
light, unless I do a 2 -3 minute stabilization run at 2100 RPM, my 912 back
fires like a shotgun when I turn it off. I have newly rebuilt carbs, perfe
ctly balanced carbs, plugs at .024. The engine runs perfect, uses no oil.
My exhaust stacks are heat-wrapped. As severely as it backfires, I am afr
aid I am going to damage my exhaust system.
Anyone else ever experience this? Anybody know what is causing it. Is som
ething wrong or is this just the nature of the engine.
AS always, thanks for your help. This forum is a fantastic resource.

That's a nice skid but not mine. If you are on the BBS Matronics forum just hit

| Subject: | Fuel pump dripping |
Kolbers,
I developed two concerns while flying yesterday. Maybe that's the price
you pay to have weather suitable for flying in January in PA!! I do two
seperate posts...
I have both an electric and pulse fuel pumps and I take off with the
electric pump on and switch it off when I'm at altitude. Yesterday when
I was preparing to go I found fuel dripping from the hole in the bottom
of the pulse pump. When I turned the electric pump off it stopped,
turned it on and it dripped again. I took my last flight but had the
electric pump off from TO to L.
I don't know what's inside the pulse pump or the workings of the
electric pump, so if any of you are familiar enough with either or both
maybe you could direct me to, first, which pump is malfunctioning and
second, in what way. I'd appreciate any input from anyone familiar,
because I'm not.
Thanks,
Dave Kulp

| Subject: | What's inside the vertical stab below elevator level |
Hi again, Kolbers,
I have a tear in the fabric circumferentially around the tube that runs
diagonally from the boom tube to the tail wheel and a wrinkle up both
sides to the upper tube. I don't know what goes on inside the
triangular piece of vertical stab beneath the level of the elevator, so
I don't know if the problem is just fabric or something with the tube
inside. Does anyone have a photo of the tubing of that section of a FF
uncovered so that I can see what it's like inside? Or perhaps a scan of
p. 5 of the builder's blueprint? I don't want to cut the fabric if it's
only a fabric malfunction, but I don't want to land with a broken tail
wheel assy, either.
Thanks for any enlightenment. Something most of us can use from time to
time...

The tail wheel spring slides into the steel tubing of the tail post assy.Bu

to it and goes up the rest of the way to the fuselage tube.That aluminum t

Had one on my Mk IIIC. Lasted about .5 seconds when the runway was about 3
feet too high. About the only thing I can imagine it might be good for is
preventing a nose over if you get a little anxious with the throttle,
otherwise it's just dead weight.

To help explain the assembly, I marked all of the steel welded components
that make up the boom tube attachment ring and vertical stabilizer post with

David, Stainless is tough but not strong, depending on alloy, you'd have to
get into the precipitation hardened alloys to get close to what 4130 gives.
Paint can make it as pretty as stainless and it might actually do some
good. I still think if you use a judicious hand on the throttle and don't
mash the brakes they are dead weight and drag.
