Small Beta type stirling engine not running

Post by senss1234 » Wed Nov 07, 2018 7:21 am

Can any one trouble shoot?
Please take a look at my prototype:

Description:
Steel wool displacer, lose fit - will fall on its own weight
heat source - Biogas
Ballon as power piston
Checked for leakage, nothing found
Flywheel - used 2 to 5 CDs, with no outcome.
Water cooled

I think I can see why the motor wont work, you have a large clearance around the displacer rod, you need absolute minimum without binding/friction.
