Kelly Troyer Dyke Delta/13B/RD1C/EC2 -------------- Original message from "Ed Anderson" : -------------- Not quite correct, Rusty. My 2900 is a DCOE type (Throats are closer together - like 90 mm center to center whereas the IDF type are more like 120mm) and has the 4 injectors. Perhaps they have discontinued the 4 injector DCOE type.

Thank goodness....wouldn't want it to be too easy. Paul I just looked up the details on this. The 2900 is a "DCOE" type unit, which I believe relates to a standard size of carb that was popular before I was born. It doesn't appear that this size TB comes with an option to have 4 injectors, but to be sure, you'd have to ask TWM. You probably don't want to mention airplanes, since they've been fairly against the idea in the past. The 4 injector unit I have is the 2930 "IDF" type unit. Again, ancient history standard sizes. These appear to all be 4 injector units, in sizes from 40 to 55* Cheers, Rusty (still working on the single rotor ebay guy) *- Yes, I know there are other sizes :-) --NextPart_Webmail_9m3u9jl4l_11280_1115433655_0 Content-Type: text/html Content-Transfer-Encoding: 8bit
