Using a timing light is the ultimate for timing accuracy. I generally sit on the right wing while checking the timing with the engine running. This works well when done in low light, such as at dusk. As Phil mentions, adjustments are made with the engine off.

However, I would like to suggest that aerosol carburetor cleaner or aerosol throttle body cleaner is a better choice. The ether in starting fluid is HIGHLY volatile and poses the threat of detonation. Carb and throttle body cleaners are safer. Charlie Kuss >What's nuts about it. I do it all the time.

I can send a copy but my edition (Rev L June 2006) has so many errors, it's no wonder they require it be supplied with a pre-built harness. There is no such thing as a simple question!

I personally know of 2 aircraft with Fadecs. One has fallen from the sky at least twice, the other is not working well. I fly with that one fairly often, and one time on a very long cross country. With 800 hr mags I consistently get much better fuel economy than the fadec as well. I now have an E-mag on the right and a 950 hr Slick Mag on the left, both are working well. Fadec and other systems may be a thing of the future, but that future isn=92t here yet. As always, if your goal is to =91experiment=92 and help =91blaze the trail=92 for the rest of us, then go for it. Otherwise, spend your $$ on something else.

I=92m looking at FADEC for an RV-7/XP-360 combination=85 I must be too old-fashioned and resistant to change but I am not enamored with FADEC. Seems like a costly option. Have you considered things like the P-Mag? Obviously you can do whatever you wish and my opinion (perhaps not well-informed at that) should not dissuade you from doing whatever you want. But given X amount to spend on an aircraft, I would think that going with some new glass panel with terrain avoidance, great mapping, weather etc offers more to the flying experience and safety than FADEC. Oh yea, big screen glass too! Ron Lee 10/20/2006 -- 10/20/2006
