I now have a number of parts for this engine but need some advice as there seems be a slight difference in the piston and liner design.
I have got a rear induction 6.5cc with drum valve, and the con rod is
circular rather than flat like the other SRII model I have, it also appears to be longer and the wrist pin is set higher in the piston to offset this.
The exhaust port is also split into 2 halves, with a thin liner bar running up the center, my other SR II engine does not have this.
Is this a later model for ducted fan use ? Do you carry spare piston & liner
and con rod for this type ?
Can you tell me what the port timing is on these models so I can calculate pipe length.
Thanks
Martin
