Change the oil...
If it has any significant time on it it will be in need of a change out, oil will shear down over time...

I'm a fan of Amsoil products and will probably use theirs if I can afford it, gotta figure out how much my reservoir holds. The owners manual doesn't show the capacity.
I changed the hydro oil in the Encore Premier Walkbehind last night and found that 9 quarts (as specified in the manual) is to much!
I drained the hydro tank and changed the filter, after about 8-1/2 quarts it started overflowing.. So I figure there was still some old hydro fluid in the lines/pumps.
I decided to go with a cheaper brand oil, SuperTech 20w-50 Synthetic.. Walmart brand!
