Thanks for the conrod tip , Im doing a little machining when I can , I like the Silver Swallow its a good subject for a rebuild, boy the casting is bubbly and has cracks and faults when I cleaned it

crank 50% done

piston 50% done


Cylinder honed


rod

cant make up my mind whether to use a longer rod and space the cylinder upwards , ,,,, just dont know yet

By the way its a flight engine only , it will get half a tank run in maximum , so I will set it up on the loose side <br type="_moz" />
