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 :-)
