Orientation of object is wrong only first time I call function. How can I fix that?

This is code that spaws Soda and attaches it to player. The problem is that first time the function is called it spaws Soda is wrong orientation. Second times it's called it's as intended.

Images for reference: image1, image2

local items = {}
	
	function items.get(player, item)
		local successful = false
		local object, pos, ang
		local animation = Instance.new("Animation")
		
		if player.PlayerData.Item.Value == nil then
			--Get item type
			if item == "Soda" then
				object = game:GetService("ServerStorage").Soda
				animation.AnimationId = "http://www.roblox.com/Asset?ID=5162117084"
				pos = CFrame.new(0,-1.3,0)
				ang = Vector3.new(0,0,-90)
			end
		
			local arm = player.Character["Right Arm"] --Spawning and position
			local clone = object:Clone()
			clone.Anchored = false
			clone.Parent = arm
			player.PlayerData.Item.Value = clone
					
			clone.CFrame = arm.CFrame:ToWorldSpace(pos)
			clone.Orientation = ang
				
			local weld = Instance.new("WeldConstraint") --Weld parts
			weld.Parent = clone
			weld.Part0 = arm
			weld.Part1 = clone
			
			--Animation
			local animationTrack = player.Character.Humanoid:LoadAnimation(animation)
			animationTrack:Play()
			
			successful = true
		end
		
		return successful
	end

return items

If you want to get past the problem of it not working first time what you want to do is call the function first, delete the soda, then call the function again and hopefully the soda should be in the correct place.

So I think I figured it out. I swapped right arm for torso and adjusted the position and rotation and it worked. Thanks @Gooncreeper for contribution
