Testimonials from Challenger web site blog:
I replaced my first set of Rotax carb sockets and throttle/enrichener cable
boots at 200 hours. They were starting to get cracks on the outside. I
replaced them with JBM sockets and boots and have a little over 200 hours on
them. They still look great--no cracks whatsoever.
-Mark

Hi Mark. We built our Challengers at about the same time. I had the same
experiences with the carb boots and replaced them at about the same times.
The JBM's are still holding up fine with close to 500 hours.
-Joe

Hi Flyers!   I feel kinda funny telling mostly guys about this (not a girly thing) but, I just
wanted to share an experience that I had today!
With the WX forecast OK, It was the day I'd set my goal & schedule to get out to
Sawyer's Airfield (my home field)
& look over any possible weather damage or neglected items I had not gotten around
to.
One such item was simply replacing the Rotax carb boots that connect the dual Bing
carbs, with the new JBM boots I had bought a few months ago.
They're made from a "superior blend" of rubber, and are reported to last much longer
than the Rotax ones.
My existing Rotax boots were still new looking with only a minor dullness and still
seemed to flex a little.
I've seen them on other Rotax equipped aircraft with an appearance more dull & dry
looking.
I'd read stories of carbs falling off, or high temps, etc.
Well, it wasn't ideal flying conditions with an 11 Knot 90* cross wind, and my broken
wrist still healing. My friend Tony helped me replace the old boots with the new ones.
I explained to him why I felt spending a little extra money and replacing a known "weak
link" in the power plant was beneficial for my peace of mind.  The old boots showed a
few superficial hairline cracks after he started distorting them.
He then squeezed one into an oval shape and "poit" it split wide open!
"Dang!! Looky There!!"
I had run the engine for 20 minutes a few hours earlier, but not above 3000 rpm.
One cylinders EGT temps a "skosh" higher than the other, but not anything that would
have given me a "no go"decision.
Anyway the point is, don't trust a simple visual inspection of parts that are getting  kinda
old but still look "fair"!  I'm sure I could apply that to other things too, but we'll just let
that go for another discussion!
I look forward to getting to fly again soon!
Have a good one!........Jackye     From: Jackye Reynolds <skyjackye@yahoo.com>
NOTES on Rotax 277 with BING model 54 carburetor:
Don – Just wanted to let you know that the straight manifold does work on my 277.
The carb tilts slightly downward but apparently not enough to mess up the float level.
The engine runs just fine, CHT and EGT temps are good, and the shaking of the
carb at idle is significantly reduced because your manifold is shorter and therefore
more rigid than the factory curved one.  In addition, your clamps are way better than
the Rotax factory clamps. I’m a lot more confident that the carb will stay attached
with your set-up.  I’m a very happy customer!  Thanks,   Martin Barackman
NOTES on Rotax 912 Rubber Flange Carburetor mounting socket manifold:
Rotax provides an internal aluminum ring on some of their flange sockets sold as
replacements on the 912 engine. These rings should
NOT be used with JBM rubber
flanges.

SOLD OUT
Just a note to say thanks for the prompt attention you gave my order. A month or
so ago, a friend of mine and I noticed that the carb sockets on his Air Creation
Twin 582 were getting a little checked and needed replacing. We found your
website and ordered them from you. We are very pleased with the quality of them
and the prompt shipping we received. So....I ordered 2 new silencer box boots for
the 582 and a carb socket for my Racer 447.
I ordered them on Tuesday 7/3/12 and I received them today, Friday 7/6/12. Even
though we discussed the possibility of a delay because of the 4th holiday, they still
showed up. You must have made a special trip to the Post Office or something.
Whatever you did, it is VERY appreciated. I find very little satisfaction with most
companies I do business with and I can't begin to tell you how pleased I am to find
a company who makes a quality product at a very competetive price and pays
attention to detail.
Thanks again. I will be doing business with you again and I have already sent
friends of mine your way!

Hi,
I installed your carb boots on my 503 about 5 years ago.  So far they still look
like new.  Is there a failure mode I should be looking for?  The original stock
rotax boots would 'warn' you by cracking showing eminent failure.  So far yours
show no sign of failure whatsoever.  I'm wondering what to look for?
Thanks,  Bill Volcko
