"Start to Inf." vs. "start V-ing" [duplicate]

I want to know about usage of "start + action" and "stop + action". Which one of followin are correct or preferred? For ex.

When shall I start working?

When shall I stop working?

Or

When shall I start to work?

When shall I stop to work?

Does it depend on a context or on the action itself? Are there any rules that I can apply to phrases contain "start" and "stop"? Or maybe there are some differences in meaning?

Since the start or stop of an action, like working, is part of the action itself, both are possible, although the 'to' construction is somewhat, as a little Google Search shows, more common in the UK.
