Setting up a timer for rate of fire on my instantiation

Unity Engine

I cannot get this code to work for the life of me! So now I come to you the great Unity Community to give me a helping hand! Please show me what I am doing wrong. Thank you!

public var deathBall: Rigidbody;
public var ballSpeed: float = 25.0;
private var reloadTime: float;
private var canShoot: boolean;


function Start()
{
reloadTime = 0.0;
canShoot = true;
}

function Update () 
{
	if(canShoot == true)	
	{
	MouseClick();
	}
	reloadTime += Time.deltaTime;
    if(reloadTime >= 2.0)
	{
	canShoot = true;
	reloadTime = 0.0;
	}
	else if(reloadTime <= 2.0)
	{
	canShoot = false;
	}
}

function MouseClick()
{	
	if(Input.GetButtonDown("Fire1"))
{
	Instantiate();
	canShoot = false;
}	
	
}

function Instantiate()
{
	var newBall : Rigidbody = Instantiate(deathBall, transform.position, transform.rotation);
	newBall.velocity = transform.TransformDirection(Vector3(0, 0, ballSpeed));
	Physics.IgnoreCollision(newBall.collider, transform.root.collider);	
}

UPDATE: I adjusted the time limit, which is 2.0 in the above script to .05 and it shoots at a low rate of fire. However, now other then the second shot it is not following the .05 limitation. It is kind of random. For example, it will shoot 3 balls, then two, then allow three again. Getting closer!

I figured it out!

function Start () {
	while (true) {
		while (!Input.GetButtonDown("Fire1")) yield;
		Instantiate();
		yield WaitForSeconds(reloadTime);
	}
}

function Instantiate () {
	//...
}
