I have been having a challenging time servicing Aristo Eggliners and an FA.
Those engines that "never need servicing? are a joke. Don’t believe it.
Anyway I found a parts diagram today that may help. I never saw it before.
It is a parts diagram for the Eggliner and I believe the same goes for the newer FAs. You will find it at http://www.gscalenews.com/pdf/aristo-craft/22700.pdf
