I just acquired a slightly used TT Pro 120 2 stroke (6 flights, no crashes or hard landings). He was not happy with the power/speed for the plane he had it in, and upgraded to a Moki 2.10. The person threw in (besides a pitts muffler and stock muffler) a new pump for it (The pump has the TT logo, but says "A-BAN" on it) . I received the paperwork for the engine, but nothing on the pump. I think I got a "good price" at $50.00 for everything.
I have tried a Google search, but can not find the TT home page or any info on the pump.
I know the pump bolts in in place of the backplate, but that is all. I presume it is qoing to require adjustment of some type and I am not sure on how to adjust it.
Will I still need to use the pressure tap from the muffler with the pump?
There was also an additional screw and gasket. The additional screw would go in the center of the pump, but it has a larger hole in the center than the one that is installed. Does it make any difference which one is installed ?
Any additional comments on the engine/pump are welcome.
Thanks
