valjoux 7736 chrono hand will not reset

Question

Hi all, i have a nos 7736 but the chrono hand will not reset to 12, it always stops just short before or after, i have tried 5 times to remove and refit the hand by resetting and then keeping the pusher held in so i am thinking maybe there is an underlying problem. i am going to part service that part of the watch before i try again in the hope that might help as the movement has not been used in years but is there a way of using an eccentric to finely adjust the hand and if so where is it located, also does anyone know where i could get a proper chrono movement holder, i looked on cousins but all they had was 7750s so i bought one but it is to small. 

thanks

Reseted to zero the hammer should press against the Heart of the Chrono Wheel and the wheel should really be fixed (Look from the side for a gap and try to rotate the wheel with a tooth pick). On the other hand there must be a small gap between the hammer and the heart of the minute counter Wheel.
