Why is oil seeping into the cylinder while being stored? I have a 324LDX trimmer and I store it vertically on a hanger against the wall in our shed. This is the 2nd season in a row that I've had to take it in for maintenance. The recommendation is to not store it tipped in any direction for an extended period of time. Why is this happening and what is the proper way to store it? I thought I remember reading somewhere that this model of trimmer did not have any issues with whatever angle it was held or stored at.
