Try adding some weight to the flywheel approximately 90 degrees to the left (counter-clockwise) from that peg that is already on the flywheel. That's the spot where it has the most trouble, and a weight right there (not too heavy) would help it through and even out the work load through the cycle.
Great idea! I assume your displacer is cam shaped...Did you try putting some re-generator material to fill the "gap" (or flow) part of your displacer?
@sizenevermatters thanks! the displacer is made from two half-cylinders of styrofoam sticked together and then covered with paper (I suppose styrofoam disappeared because of the heat and it's almost empty inside now). I don't use any regenerator. Do you you think I should?
@adambus77 Well, i was asking myself the same question :) The regenerator is used when one system has "reflow" of the working gas...In case of eccentric displacer some opt to use spongy or metal wool like material to regain the heat as the air flows through it...But in your design...I don't know if it's applicable...I'm still thinking...And maybe try re-balancing the flywheel, it looks like it's not balanced...And have a look at "Design analysis methods for Stirling engines" article...
Just find a way to separate hot and cold side by a thermal insulate material (eliminate thermal bridge) and make the space between displacer chamber and power piston smaller as possible( your blue pipe is very long , youy cannot connect the power piston directly to the chamber ? ). Btw , cool stirling engine , five star !
The driven resistance in this engine comprises an old balloon. Compare that with a wankel engine of similar displacement with all its rotor tips, eccentric and side seals all rubbing the bore.

@PyroEvil Well, I have too many ideas and projects but maybe I'll try to improve it somehow. Thanks mate!

nice...
i fail to see why no one has modified the wankel engine to run stirling.
