Paul,

It does have the 12 blade compressor, I'd have to go measure the diameter. The engine was new from Jet Joe about 5 months ago so I'm pretty sure it is a later model JJ1400.

I may go ahead and open it up to check the nozzles etc. Just hope the compressor nut releases before the turbine wheel nut so I don't have to get it balanced again. Also, before I do anything I will measure thrust with it in the plane as it is now and then again after working on it and with the two different exhaust cones so we'll have some numbers to compare.

Also Paul, did you have the single or two piece exhaust cones on yours?

Mike
