there is not sufficient power at first to overcome the inertia, so external work in the form of pushing it by hand is needed. however once started the momentum of the flywheel keeps the engine running?

Welcome to PF, mh1985! :smile:

Just like a regular engine, the Stirling process consists of 4 phases.
In only 1 phase does the engine actually generate power.
The flywheel keeps the engine running through the other phases.
(That's also why a regular engine needs a starter motor.)

I suspect that if you bring the flywheel in the right position, the engine should be able to start itself when heated.
