Narrative: We completed pre-flight and fueling; stocking and cleaning of aircraft. Loaded passenger bagage and cat on board. During taxi out while running the taxi checklist when testing the Thrust Reversers (TR) the Captain stated that the TR levers felt different. The test tested normally. We then completed are flight to are fuel stop and then on to destination. We were wondering if the levers were some how installed wrong because they had under gone maintenance two days before. They just did not feel right; it was hard to get your fingers under the levers. The next day during pre-flight we called maintenance and sent pic's of the TR levers and asked if they were ok. When they called back stating that they were not right and that they needed to be adjusted. The aircraft was written up and is waiting for maintenance. After completing maintenance on the TR's they should be test to make sure that they are working correctly.


Second narrative: We preflighted; fueled and awaited passengers. Our passengers boarded and we taxied out of the FBO down taxiway G to hold short L. On the taxi out; I called for the taxi check and when the first flight of the day Thrust Reverser (TR) check came to; I placed my hand on the levers to deploy and something didn't feel right. (kinda restricted in space or obstructed) I couldn't put my finger on what was exactly different; but the TR's did deploy normally (successful test). I suspected that the rigging might just be more tight since the TR's had been worked on a few days ago; clearing MEL 78-XX-XX; TR's easily deployed with little pressure. We taxied on and the flight continued without incident; We stopped for a fuel and we were to continue to DEN; First Officer (FO)'s leg. The FO did a TR check; per my recommendation to get his opinion. He too said it felt strange but also believed perhaps it was tightness of the rigging. This flight too continued without incident. The following day; this something's not right feeling compelled me to take a few pic's of the TR assembly and forward to Maintenance Controllers. I then called them up; asked them to review the pic and please go out to the hangar and compare with a XL/XLS. The controller grabbed a Chief Pilot; and they compared the pic and an aircraft. The got back with me and said I was correct; the assembly; (throttle detent window) had been installed backwards. They asked me to write up the discrepancy . Maintenance then arranged a vendor at KDEN to come out and correct. We were delayed quite a bit and this impacted a pax flight heavily. I suspected something was wrong as it didn't feel correct. I believe that I trusted that the maintence was performed correctly and that lead me to disregard my suspicions. In the future; I believe I shall trust my instincts more and return to the originating point; or if enroute; seek the inspection or opinion of our mx at the point of landing before moving aircraft further.


Synopsis: CE-560 flight crew believes that something is not quite right during a thrust reverser test on taxi out; but the test is successful. Two legs are flown and the next morning pictures of the throttle quadrant are sent to maintenance for a professional opinion. Maintenance replies that the throttle detent window assembly has been installed backwards and needs to be corrected before further flight.
