Why does my part keep rotating when I don't want it to?

I have a few parts with a BodyPosition and a BodyGyro. The parts keep spinning and I've tried to fix it.

Here is a little bit of code from what I'm trying to make:

local m = Instance.new("Model", char) m.Name = "fwdjawioffresetyoudwasdrmompphasdwhwwukcalloverit"

function BODYPOSITION(PARENT, POSITION) local BODYPOS = Instance.new("BodyPosition",PARENT) BODYPOS.Position = POSITION return BODYPOS end

function smooth(p1, p2, sp) local f1 = BODYPOSITION(p1, p2.Position) f1.MaxForce = Vector3.new(sp, sp, sp)

local g1 = Instance.new("BodyGyro",p1)
g1.CFrame = p2.CFrame
--g1.D = 20
g1.P = 300
g1.MaxTorque = Vector3.new(0, sp*2, 0)

thread(function()
	while true do
		Swait()
		f1.Position = p2.Position
		g1.CFrame = p2.CFrame
	end
end)

end

local E = 0.75 local ZZ = 0.9 local k = Color3.new(1, 1, 1) local br = Color3.new(0, 0, 0)

local heyj = 4000000

local temp = Instance.new("Part", m) temp.Transparency = 1 temp.Size = Vector3.new(1, 1, 1) temp.CanCollide = false temp.Anchored = true temp.CFrame = cfra temp.Name = "Base"

local hedi = Instance.new("Part", m) hedi.Transparency = 0 hedi.Size = Vector3.new(2, 2, 2)*E hedi.CanCollide = false hedi.Anchored = true hedi.CFrame = cfra hedi.Color = br hedi.Material = "SmoothPlastic" hedi.Name = "Head"

local f1 = smooth(hedi, temp, heyj)

"cfra" is where the part should be CFramed to when I instance it.

By the way, the script I'm making is for a game named "Void Script Builder". I mainly make scripts there and I don't make many games anymore.

(by the way the code ends after this line: local f1 = smooth(hedi, temp, heyj))
