If your car or motorbike should ever need a bit of tinkering, Chennai is the place to come. Tinkering here has been raised to a service industry.
I'd always taken tinkering to mean fiddle-faddling about to little effect - with the basic requirement being that the 'tinkerer' has no expertise at all in the task they are trying to fulfil.
The online dictionary back me up in this: tinkering, it declares, is an 'attempt to repair or improve something in a casual or desultory way'. It offers as synonyms: 'try to mend/improve, work amateurishly on, fiddle with, play (about/around) with, toy with, trifle with, dally with, dabble with, potter about with, fool about/around with'.
