FS2002 Throttle Problem

Does anybody have a "Fix" for the FS2002 Throttle?
I have a CH Products Yoke with 3 levers (USB).

I want to use one of the 3 levers to control the throttle settings.
When programmed into the FS2002, the throttle lever works to some
extent.

When the throttle level on the yoke is fully applied (Full Throttle), the
SIMs throttle indicates only 3/4 full, amounting to only 2300 RPM.
To increase the throttle to full RPM (about 2500) I need to use the
mouse pointer to click and drag hte throttle icon.

Also the opposit is true. If I pull the throttle all the way back (on yoke),
the SIM indicates 1000 RPM. To get it lower, I need to click and drag
the mouse pointer again to bring the RPM to idle.

Any help would be greatly appreciated.
