Sieg hae01-1/Grizzly 8101 piston setup.

G`day to all.
I have just finished machining the material kit of this engine and have had no success on running same.All machine work was done to specs.The problem seems to be the initial position and timing of the displacer and the power piston,as there seems to be a lot of conflicting opinions out there.
As this was not a pre machined kit,I believe that this particular engine is a bit hard to get running.The displacer has suggested clearance and the power piston passed the "spring test" in the bore.There is negative friction in any parts and freewheeling is good.
At 78 years young ,I am getting a bit frustrated with the end result, as this is my first attempt at making one of these engines.
Regards,Bob Kirk.
