I will put the original strong springs back on today ! I hate the pull that they have but better to be assured of full power and no accident !!!

I did not know that both oil pressure sensor and fuel pressure sensor do have a separate connector for an additional warning light. That sounds perfect. I will get my Rotax in February 2008 and hope to have the same sensors.

The 100 hp engine may indeed need 1800 rpm idle but the 912UL does not. Ours is set for 1500-1600 rpm idle speed when fully warmed up. Setting it cold won't do you much good because it will change when warm. The Allegro is a floater too and anything above 1600 rpm idle (912UL) will make final approach difficult, just as you have experienced in your Kitfox. Roger and I have had this discussion before.... search the archives. One thing no one has mentioned yet is this. When you buy someone else's experimental aircraft, you may be in for some unexpected surprises. Are you sure you have the Rotax/Bing supplied springs on the carburetors? If a previous owner lost them and bought stronger hardware store springs, instead of the more costly Rotax springs, this could explain the difficulty your were having with holding throttle position.
