I said screw it, and flew it home with only one mag firing. (No point in getting into the wisdom of this move...I know it was stupid) The point is, has anybody else had any problems with losing a mag, or are you all changing the rotors and caps at the suggested hourly intervals, and gluing the rotors on? The second question is, what has been the condition of the rotors that you've removed? Are the rotors all wallowed out where they mount to the distributor shaft? I checked the rotor in the other mag and found it exactly as I had installed it many (can't recall how many) hours ago. So I now know that my rotor installation procedure is good, and both rotors now have been installed using the same procedure.

I keep one on my plane similar to the same logs that are kept on certified units, so I can tell how long components have been in service. I also keep the engine log. Once I get the 912 running well I'll probably sell the 582 FWF complete with the engine logs which describe all the maintenance on the engine since I've owned it. Sounds like a lot of paper work but really it's not too much and I does tell me what I've done and to one extent or the other where to look for problems as the arise.

I replaced the caps and rotors at 250 hours not because of problems, but because the engine manual calls for them to be replaced at 200 hours. When removed, both caps and rotors were working great and showed no abnormal wear at the 250 hour point. I feel they could have gone to 500 hours with no problems, but I believe in preventative maintenance. I change oil and filter at 25 to 30 hours and plugs at 100 hours. As you know, all these replaceable parts on the Jabiru are inexpensive and readily available at auto parts stores.

I'll get the numbers tomorrow, maybe, and post them then.

I didn't glue the replacements (Bosch) on, and in time, both became loose. I've finally found replacement parts that I'm happy with...Standard Brand caps, and Daiichi rotors from Car Quest. I've now got the set-up I'm happy with, and time will tell if the epoxy is the secret to holding the rotors on, and allow the rotors to "live out their lives" like they should. I'm not cheap, it's just a pain in the rump to change them with the limited room that I have. Personally, I feel that only 200 hours for rotors is way out of line...they should last at least twice that, if not more. I follow the 25-30 hrs for oil changes and filters, though.
