Start the motor for a couple of minutes then shut it off. Put car in 1rs gear and start it...most will start and take off.
Now drive it in 1rst gear. Push and hold the clutch pedal in, get up to 10-15 mph then back off fast, then hit the gas again. I've unstuck vws, tractors,A's and motorcycles this way.
A farmer back in 73 taught me this trick.
