how do I remove the carburretor from the engine?

Well, why not just do a Google search for a manual? It would have taken you all of 2 minutes - oh, and the effort of doing it for yourself bu no, you were content to wait for someone to do it for you.

Start here:

That'll do for starters. Plenty more out there if you are prepared to search
