Have been working almost every day for the past few months. Really seeing some progress now. Almost ready for the engine. Total hours: 895 (lots of work in priming and painting) Best regards, Johann G. Iceland.

Norm: The question you should ask is whether the Jabiru engine that is having problems has CHT's and EGT's on all the cylinders. If they do not, the possibility of overheating on individual cylinders is always there. My feeling is that the Jabiru engines are clearly superior to the heavier American iron but; because they are aluminium, they do need careful monitoring. Careful monitoring requires the continuous access to all CHT's and making adjustments to ensure all cylinders are approximately equal in temp. We changed spark plugs yesterday that had been in operation for 100 hours. The plugs for the #4 cylinder which was running within limits but higher than others was readily discernible. We made one more tweak to the airflow for cylinders 2, 4 and 6 as a result.

During the last flight the engine started to run very rough and lost some power. I was able to land save. Did a thorough check of the engine, but couldn't find anything. When I did a test run, the engine choughed very briefly during the magneto check. However, when repeating the magneto check this did not occur anymore. Today, I did another runup. The engine lost RPM when I switched off the left magneto. I could not reproduce this effect. Anybody with an idea or a similar experience? My best bet right now is that one of the wires from the starter key switch is damaged. Thanks Thilo Kind ________________________________ Message 4 _____________________________________ Time: 03:56:26 PM PST US From: "Bernie and Alison Garrett" Subject: Zenith-List: CH640 --> Zenith-List message posted by: "Bernie and Alison Garrett" Hi, I am new to the list and have been looking for a 4 seat metal kit for some time now. We have just moved to Vancouver (Canada) from the United Kingdom where the building of 4 seat kits is very much more restricted. The CH640 looks a good design, but I must admit I haven't looked into the insurance costs yet! Most of my time so far has been spent in low wing designs, mainly the Socata TB10 and some in the new Diamond Star DA40. I also wondered what the grass field performance would be like for this aircraft, how many are being built and what Zenith in Canada are like to deal with. So far Mathieu seems very helpful. I must admit I would also like to change the yokes to a Cessna/Piper style as they look a little narrow and possibly change the Instrument Panel, but I guess those things are pretty straightforward compared to building the rest of the kit! Anyhow, our objective is to build a 4 seat aeroplane suitable for touring for myself, my wife and our two daughters (currently 7 and 9) had any feedback is welcome! We are keen to send off for the empennage and fuselage kits, but I guess we need to look at all the options before committing ourselves to a major expenditure.

Corbalis" Subject: Re: Zenith-List: Problems with Rotax 912 --> Zenith-List message posted by: "Leo J. Corbalis" Rough running could be caused by bad ground lugs on the 2 ignition modules. A bad ignition switch wire will let the engine keep running when you shutdown. You have to cut off the gas to stop the engine. This was the subject of an advisory from Rotax a long time ago. The ignition coil ground lugs are another spot for trouble.

With the Canadian tree density and terrain, the 801 might serve you better in the long run. Get a flight demo in the 801 before you make up your mind.

I am building the CH-640, if you would like you can visit my builders page at: http://www.madbbs.com~jpaden I should have mine in the air this spring and I fly a CH-300 now. We love our ch-300 but need a larger aircraft since my children are now 11 and 13 and getting to big for us all to fit in the CH-300. Jeff Paden
