Initially I would concentrate on three positions, zero, 4.6 and 50.5 degrees on the metering unit. Zero, 2.5 and 40 degrees throttle respectively. If these positions are correct then all other check positions should fall into place.
Ensure that all pointers read zero and that throttles are closed on the stops with no free play and also that the metering unit is on its closed stop. Adjust the throttle setting tool via the knurled nut to open the throttle to 4.6 degrees metering unit and 2.5 degrees throttle. If this is not correct, recheck the zero setting and also that all three pointers start to move at the same time. Continue to open the throttle to give 50.5 degrees on the metering unit. The throttle indicator pointer should show that both throttles are 40 degrees open. If this is not so, release the lock nuts and adjust the double-ended (left- and right-hand thread) throttle rods, each side to double the error (i.e., if the reading is 42 degrees then double this to read 44 degrees, or if 38 degrees adjust to 36 degrees, and retighten the lock nuts). Adjust the tool to return the metering unit to zero on its closed stop and release the clamp bolt on the outer throttle levers and reset the throttles to zero on the stops, with no free play.
