I sold my first product startup that way. It was a part-time effort the whole time-- never made it to FT before we sold.

Part-time is a great way to run an experiment-- if it's a simple one. There are lots of great startups that start as weekend projects-- but obviously if you bite off a HUGE project, part time just won't play.

If you can set aside 1-2 nights a week (and 1 weekend day per week) to crank away for 6 weeks and release something decent, I say stick part-time and give it a whirl. If the project is more complex than that or you can't set aside that time (for you and your partner), then momentum will probably get to be a problem.

But, generally-- fulltime wins.
