I have decided to buy a second hand carby from the wreckers and replace my current carby that is giving me issues.

Can someone experienced give me some advice on what parts I need(eg. gaskets, hoses, which ones), what to watch for when doing it, what tools I need, would I need to tune it or adjust anything, do i need special lubes or liquids, etc. any links to tutorials or manuals on how to do this, etc.

Any help appreciated : )))

Below are pics of the carby that I bought since my current carby had the following problems which caused high idle and black smoke:

Carby requires overhauling
Choke/Wax pellet not working
Power vale fault(I presume its a mistype and should say valve)
Vacuum leak from carby intake rubbers

Looking at my carby below, by replacing my old carby with my new carby, will it fix the issues mentioned above?
