Need some Help

From: Graham Selick

I am in need of a good cylinder and piston plus the clip to retain the wrist pin for a   Nelson  2.5.  I purchased a nice engine, but apparently the previous owner, for some inexplicable purpose.  had disassembled it and failed to properly seat the circlip holding the pin. It let go at 25K+ rpm on the test stand and totally ruined the piston and sleeve.

Hopefully, somebody on SEN can steer me in the right direction for a new or good piston, cylinder and the wrist pin retainer.

Thanks,
Graham  Selick  – gselick@bellsouth.net
