How to lean a bing You understand this system correctly Lynn. The advantage of the electric pump is the ability to be controlled by an electronic device. So, a cab engine can be controlled like an injected one. Electronic Controlled carb advantages : - Very easy to adapt - no problem in case of electric failure Electronic controlled Injection advantage (single injector) : - better fuel vaporization (as Ellison and Rotec TBI) But, as a lot of people reports, the big deal is to balance the intake of the engine...

How to lean a bing Hi Jerome- If I understand this system correctly, you are putting a vacuum (low pressure) on the float bowl, so the engine is fighting against this vacuum to get its fair share of fuel, right? So it goes lean if you put enough vacuum on the float bowl? Somebody local told me about his leaning device, and it sounded pretty much the same. I think he used the vacuum from the engine going through a needle valve to control the vacuum, if I understood him correctly.

How to lean a bing Well then, I've got the best of all possible worlds, because I've got a gravity feed fuel flow into the Rotec TBI, and if all electrical systems fail, I've still got fuel. Of course, with my Electroair ignition system, I still need a battery...but then, I've got two of them, so I'm good to go, unless I'm REALLY havin' a BAD DAY! : ) Lynn Matteson Kitfox IV Speedster, taildragger Jabiru 2200, #2062, 744.1 hrs Sensenich 62"x46" Wood prop Electroair direct-fire ignition system Rotec TBI-40 injection Status: flying On Aug 26, 2009, at 3:03 AM, Jrme Delamare wrote: > J=E9rme_Delamare?= > > You understand this system correctly Lynn. > The advantage of the electric pump is the ability to be controlled > by an > electronic device.
