340 piston

I acquired a 340 for free not running started insecting it and the piston doesn't match any digrahms it's a 2 ring piston and all the diagrams show a 1 ring piston also it's a closed transfer piston and the diagrams show a open transfer piston

I looked at the IPL list on Leons' site and the Terry built saw mentions a single ring piston for the 340. The IPL is titled "The Comfort 340". See if that IPL fits your saw.
