The splitter has threaded plugs on both ends so the cables would get all twisted up as the threads are both right hand. It might work for cables that clamped by a set screw but if the cable slips up inside the housing, and the ends are frayed or splayed they get caught if the end cover. When you disassemble from the carb and starting carb ends you get the advantage of being able to inspect the the cable termination, the condition of the cable, the o-ring on top of the needle clip, the condition of the needle grooves and how the clip fits. For the starting carb you also get to inspect the rubber face of the plug to make sure it is sealing correctly.

We all need to support the New Kolb Aircraft Company. They need us , and we need them! Merry Christmas Dennis Dennis T/Gang: Let me update you a little. There is no "The New Kolb Aircraft Company". Not sure of their official name but I believe it is "Kolb Company". Brian wanted his company to look, taste, and smell, like Homer Kolb's aircraft company. He named it "Kolb Company, Inc." I may not be exact on the company name, but Travis Brown can correct me if I am wrong. Brian wants to build and kit airplanes that Homer designed, not fast, slick, pretty LSA's that fly 120 kts and cost 120,000.00 dollars. John Hauck MKIII Titus, Alabama - Got some air time yesterday. Still flying my mkIII with a 8 months of barn dust and bug/bird crap on it. Amazing how well Kolbs fly in any condition. I flew over to Wetumpka Airport to get 10 gal of 100LL. I am not flying much, just yet, and avgas stores much better than mogas and alcohol. ________________________________ Message 6 _____________________________________ Time: 11:59:16 AM PST US Subject: Kolb-List: Re: Photos For New Web Site From: "Dennis Thate" http://www.ultralightnews.com/sunfun99/kolb.html This must be a mirage [Laughing] -------- Both optimists and pessimists contribute to our society.

Am hoping the collective wisdom of our 912 folks can help me pinpoint the problem. The tach needle was jumping around erratically. It was mostly pointing to the correct RPM, but would often jump up to around 6000, then eventually settle back down to the actual RPM. This of course happening while the engine speed stays constant. Was doing it continuously throughout the flight. The Rotax tachometer is electronic. I suspect a bad ground somewhere in the tachometer circuit, which will be easy to troubleshoot next time I'm at the airplane. Anybody else agree?

I suspect a bad ground somewhere in th e tachometer circuit=2C which will be easy to troubleshoot next time I=92m at the airpla ne. Anybody else agree? Many thanks ' Dennis Kirby Dennis=2C First thing you want to do is verify all the wire connections are taken a part and retightened. (the hot lead=2C the ground=2C and the signal lead) If that doesn't solve the problem=2C then here's my thoughts... Your tach is a simple frequency counter. Since yours is electronic=2C 99 .9% of its innards are unadjustable (capacitors=2C resistors=2C transistors=2C a couple of integra ted circuits=2C and a few diodes). Either they work or they don't!! Except for one thing=3B the potentiometer =2C which that COULD create such a symptom is if the internal potentiometer is a little corroded =2C it would interpret a really bad frequency=2C thereby making the needle swing wildly. If you take your tachometer apart=2C there should be at least one potenti ometer (known as a 'pot'). I'd bet if you could spray it with electronics parts cleaner =2C it would help. You ought make sure you don't screw up it's calibration=2C though. That potent iometer is what the tach uses for calibration. I think it is the only thing inside that's adju stable=2C and possibly corrodible. If you plan on trying to fix it yourself=2C maybe you could try this=3B Start the engine=2C let it warm up. See what rpms the tach says. Then remove the tach=2C take off the hou sing=2C look for the pot. Once you find the pot=2C note where it is presently set at!! Spray a little parts cleaner on the pot. With your tiny screwdriver=2C twist a little left and right a few times. Spray it again=2C then reset it close to where it started at. Now hook it back up temporaril y to your engine with the housing still off. Start your engine=2C and turn the pot until the tach says the exact same rpm it said before you took it apart. Once you're happy that you have reset it correctly=2C put it bac k together=2C and re-install it. This is just a guess....

From: "ces308" I the past week I was able to get some glider and emergency forced land practice in with my Mark 3 Xtra ! The first time I landed on a fairway at the golf course south of our field and the second was yesterday,but was able to make the airport...both times were non-events do to the fact I had the skis on.After the first time we thought it it may have had a frozen fuel line...checked ,cleaned ,refiltered and ran it up on the ground and she ran fine...then took her in the air and again,no problem...yesterday,I took off and everything was great for about 7 minute when it started running rough and quit.After landing,I got it running again,but this time I could see gas pouring out the front of the carb.Ends up the float needle had a ridge around it and in certian spots it would let fuel pass by the seat and flood the engine out.Anyway,I have a new needle coming ( the black tip one with the stronger internal spring ) which Jabiru says will take care of the problem. Just a heads up the you Jabby Guys !

From: "Ralph B" Chris, were these forced landings due to the cold? This sounds a little scary to me. It was lucky you had skis on as it gave you more options for picking an emergency landing spot. There's nothing worse than have the engine quit. The 912 has been very reliable so far. I'm hoping it stays that way.
