I'm planning to rebuild my Carburettor at the 1989 GQ/Y60 4.2 engine.
The thing is pitch black from soot when looking into the top. So it seems about time.

I see rebuild kits for sale on eBay , any difference in Quality I should be aware of?
Once out of the engine bay what kind of problems can I encounter / prevent ?
What is a good cleaning fluid , do I really need those fancy carburettor cleaners?

Thanks !!
