"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:
(JBM) – 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"
"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!
