RE: Echo PB-1000 Blower engine
Hi,
The engine should weight less then three pounds with mag ignition, even less with CH. It is the same engine used for the First Place 1.3ci engine. Of course they make compression and porting mods for more power. The stock engine should give you good performance with a 120 size airplane. Pete can provide a free breathing muffler also. A 9mm to 10mm carb will add power too. Stock is about 7.5 to 8mm.
