Interconnected elevator trim to flaps

[cessnadriver]

Hello ALL-Again.
Well I thought I had the flap elevator trim fixed__GUESS NOT. I've gone through the procedure in the maintenance manual going on THREE TIMES! I can get the trim set at the proper degrees of trim UP and DOWN, then when I adjust the interconnect flap-trim I cannot get the proper DOWN TRIM. I only get about 5 degree, it should be 26 degrees, because of the STOP BLOCK #8 on the up cable. This is the block that presses up against the #9 block on the end of the push-pull solid wire cable connected to the Flap bell crank. DOES ANYONE HAVE EXPERIENCE WITH THIS?
Thanks for any and ALL help.
Regards, BILLS
