First off, some history....why did I go with an after- market ignition system instead of the stock Jabiru ignition?....I thought there might be a better/more modern way to fire the plugs than the old system, and I became tired of having to change rotors after the recommended 200 hours of use. Also, I was reluctant (stubborn) to glue the rotors on as recommended. After having found that it was indeed necessary to glue them on, and having some success using that method, I decided...during a rebuild of the engine...that I would leave all the distributor components off when reassembling the engine, and go with the Electroair direct fire system. Electroair had begun development on a component to replace one of the Jabiru distributors. This would retain the other distributor as the other half of the redundant ignition system. I, being stubborn, wanted to do away completely with the Jabiru ignition, and asked Electroair if they would design a system that would use a trigger wheel and two magnetic pickups, similar to their 6-cylinder engine systems. They would do this, but I had to make my own bracket to hold the two pickups, as they did not have access to a Jabiru engine for designing the prototype bracket. I agreed to this and ordered the ignition kit. To make a long story short (and to create some drama for a possible future magazine article), I got the system installed, and it is working beautifully. There were some minor "growing pains" as we sorted out some installation issues, but these are in the past, and I am now flying with the assurance that I won't be bothered down the road with loose rotors, loose distributor caps, leaking distributor shaft seals, and scored shafts that I have experienced in the past. The kit originally arrived weighing about 13 lbs, and by cutting the harnesses and spark plug wires to a more suitable length for my airplane, I got the weight down to about 11 lbs. I removed the Jabiru distributors, drive gears, caps, rotors, coils, and plug wires, totaling exactly 5 lbs. So the increase in weight for the Electroair system was about 6 lbs...a small weight penalty for such a modern dependable ignition system, and one that allows for future ignition modifications as well, which I will be looking into.

Dear Jabiru Listers,I'm getting prepared to do our annual aircraft inspectio n on my Zenith Zodiac CH601XL powered by a capable Jabiru 3300. =C2-I was wondering where is the best place to get a new set of rotors, distributer ca ps and spark plug leads. We now have 230 hours on the airplane and engine.My Son contacted Jabiru but I think the prices they are offering are a =C2-w ee bit high, I may be wrong, but I thought I'd throw it out there and see wh at advice you Jabiru wonks could add. =C2-I am also looking for accurate p art #'s so if I go to a local supplier I'm assured that I'm getting =C2-th e right parts.Thank you for yur time and cionsideration.Sincerely,Pete Paris =C2- ------------------------------------------------------------ Art School Click to become an artist and quit your boring job. http://tagline.excite.com/fc/JkJQPTgLBDtkjc2DaWmjWez7C50Sxf8ZUexPyP3AmlDiS0B yanP4JQ/ ________________________________ Message 3 _____________________________________ Time: 06:52:22 PM PST US From: "Jeff " Subject: JabiruEngine-List: Cobra Head/airbox connection to the carby JabiruUSA doesn't seem to have a source for the recommended smooth air elbow recommended from the airbox to the carby intake. Does anyone have a source? My local auto parts stores just looked at me when I told them I just wanted to look through their hose selections to find one. Seems if you can't tell them what car it goes on, you are out of luck .. It is 2 and one quarter inch inside diameter in a 90 degree elbow. This may or may not be the part they refer to as the Cobra Head. Obviously, one did not come with my FWF kit, just scat hose. Thanks ..

The turn is a little wider than 90 deg., perhaps 105-110 deg. Another short piece of straight 2.25" hose completes the run up to a bottom exit from the mixer box. A photo is at at http://n254mr.com/node/572 . There's a lot of stuff in the way in this photo, including Magnecor plug wires dangling about, but you ca n get the idea. It's an AeroCarb installation, but the Bing intake geometry would be much the same.
