Thanks for the specs. Thats half the battle. My 55 CP box o saw that is on its way to me has no piston with it to measure for comparison

You need to measure your bore to see what you have?  You say closed port? Your sure CP and 45mm then?  If so you might be able to just clean up cylinder and use that jonsered 535 45mm  piston.


That 46mm piston in those kits are.


Bore 45.93mm
Height 37mm
Head Type Flat
Piston Pin 10mm x 34mm x 6mm
Ring 46mm x 1.5mm Caber
Compression/Pin Top to top of Piston 14mm
Compression/Pin Center to top of Piston 19mm
