chainsaw holster, upside down for extended period of time

[husqORbust]

Thinking of a chainsaw "holster". Think a spare tire mounted parallel with the back of a pickup truck window. I'd like to mount a saw to holster to the wheel. The bar side of the saw flush/parallel with the spare tire. I'd grab the saw from the driver side, straight out/perpendicular to the door of the truck, or perhaps a slight angle upwards.

This would mean the chainsaw is upside down, fully fueled and oiled ready to fire while in transport.

Is there anything wrong with placing a chainsaw upside down?

I stored mine bar down for years and never had any issues if that helps. mine was on my Partol and was always in the mount, even when doing extremely rough off road stuff.
