I made a few parts for it , , a piston made out of mild steel with a 2.5 mm piston pin,,,, down from the stock 3.5 mm piston pin


Next a new rod , pretty thick,,,,

and a mild steel contra piston

Runs OK on the bench on an 8x6 , doesnt start all that well , is a bit leaky , but not too bad , its flyable

I put another tank through on the bench and it starts up from cold not bad,

Compression is still there, pictures when I get a Camera for Christmas
