Hopefully someone has an answer for me!

I tried to read most of this so I'll apologize if this has already been answered..
Is the automatic decompression reccomended? When I bought the bike it was disconnected and I've been able to start it, serious piston to be moving, we all know that; but should I buy the linkage and hook it back up or say forget it and rock the lever only?
