Recoil

Hi guys.
I need some help with recoil . I've managed to script shooting but the problem is my when shooting rifle gun doesn't get back to original position , and i can't recoil when shooting automatically.I don't know how to describe problem best.So i have variable recoil and when i shoot it should increase but when not decrease but it doesn't. Can anybody help. And go easy on me i'm still new to scripting.

Code (csharp):

1. //Shooting
2. var BulletPrefab:Transform;
3. var force : float = 2000;
4.  
5. //Rifle
6. var ammo : int = 100;
7. var FireRate = 0.1;
8. var Rifle = true;
9. var CanFire = true;
10.  
11. //Recoil
12. var recoilMod : Transform;
13. var weapon : GameObject;
14. var maxRecoil_x : float = -20;
15. var recoilSpeed : float = 10;
16. var recoil : float = 0.0;
17.  
18.  
19.  
20. function Update()
21. {
22.  
23.  
24. if (Rifle == false )
25. {
26.  
27. if(Input.GetButtonDown("Fire1"))
28.     {  
29.     if (ammo >0)
30.         {
31.              
32.             recoil+= 0.1;
33.             Fire();
34.         }
35.     }
36. }
37. else {
38. if(Input.GetButton("Fire1"))
39. {
40.  
41.     if (ammo >0)
42. {
43.  
44.      recoil += 0.1;
45.     Fire();
46. }
47. }
48.         }
49.  
50.     }
51.  
52.  
53. function Fire ()
54. {
55. if(recoil > 0)
56.  
57.     {
58.  
59.         var maxRecoil = Quaternion.Euler (maxRecoil_x, 0, 0);
60.  
61.         recoilMod.rotation = Quaternion.Slerp(recoilMod.rotation, maxRecoil, Time.deltaTime * recoilSpeed);
62.  
63.         weapon.transform.localEulerAngles.x = recoilMod.localEulerAngles.x;
64.  
65.         recoil -= Time.deltaTime * 5;
66.  
67.     }
68.  
69.     else
70.  
71.     {
72.  
73.         recoil = 0;
74.  
75.         var minRecoil = Quaternion.Euler (0, 0, 0);
76.  
77.         recoilMod.rotation = Quaternion.Slerp(recoilMod.rotation, minRecoil,Time.deltaTime * recoilSpeed / 2);
78.  
79.         weapon.transform.localEulerAngles.x = recoilMod.localEulerAngles.x;
80.  
81.     }
82.  
83.  
84. if(CanFire == true)
85. {
86.     var bullet = Instantiate(BulletPrefab, GameObject.Find("spawnPoint").transform.position, GameObject.Find("Obj").transform.rotation);
87.     bullet.rigidbody.AddForce(bullet.transform.forward * force);
88.     CanFire = false;
89.         yield WaitForSeconds (FireRate);
90.     CanFire  = true;
91.    
92.     ammo -= 1;
93.    
94.    
95.    
96. }
97.  
98. }
99.  
100.  
101.
