I've done some reading on this subject...Lots of real good info on this site, but am unsure of what piston to buy. I cannot find a OEM Jonsered 490 piston and am considering buying a Stihl 028 piston and re-cutting the dome to lower the compression if needed. Has anyone found a good interchangeable replacement piston for the Closed port 44mm Jonsered 490 cylinder? If modifications were needed, please share. Thanks in advance.
