Hi all,
just thought I would threw this in there so please correct me if im wrong but I would assume that chainsaws do not vent thought the cap because if you are operating the saw at a funny angle, say with the filler cap down then the fuel would run out the vent. My stihl vents into a funny white thing- pointing towards the bottom of the saw so it would only leak if it were upside-down!
I know if you turn a brush cutter upside-down it is likely to leak out the cap- that�s why most caps are located at stupid angles to avoid this.
Regards jay
