Here is a good overview of the "how it works": http://www.rotectbi.com/HowTBIWorks.html Rotec has some other info on their website that might help with your questions, and probably relate to the Ellison as well. http://www.rotectbi.com/ and their FAQ page at http://www.rotectbi.com/FAQ.html They are simpler than a carburetor with less moving parts (ie, less things to fail). In theory they tend to atomisize the fuel better than a carb, giving slightly better fuel economy (I was unable to verify this due to not having proper fuel flow equipment at the time, but others have reported this to be the case). Since the air path is slightly less restrictive than a carb, again theoretically the chances of carb ice forming are slightly reduced. The reason I switched is that the Rotec TBI is compatible with mogas containing 10% ethanol (E10), whereas the Lycoming carb has at least two internal parts that are not compatible, and have been known to cause problems in the presence of E10. If I were doing a new engine install, I'd likely go with fuel injection, but the TBI was an easier option for replacing a carb and getting E10 compatibility. -Dj -- Dj Merrill - N1JOV - EAA Chapter 87 Sportsman 2+2 Builder #7118 N421DJ - http://deej.net/sportsman/ Glastar Flyer N866RH - http://deej.net/glastar/
