I just pulled a 2 speed Honda out of the shed to have a look at and get it going, I new it had had ethanol fuel in it when I looked at it quickly 6 months ago. Today I checked the oil which was very clean but I had to drain 650mm out of it before I could get it to stop smoking. Is it too hard for people these days to just Google how much oil to put in a motor mower or how to read the oil level on the dipstick, it isn't too complicated. Anyway I have a nice running GXV140 motor sitting here now, and I think the 2 speed might be working as well, it seems to engage ok. Bit of a win here
