I plan on trying this next weekend (pumping oil) seen one video on youtube seem to work okay. If not I will drop the pan and clean filter or replace.
I guess the purging is pretty much the same on all of these
worked okay with the pump I got almost 3.5qts out. All I did was pump all the oil I could from the filler open, then raise the front of mower as high as I could then pump some more...Runs great..seems a bit faster to me.
