I’ve got a 72 and it’s a freaking terror of fun I don’t know what could go wrong with Honda also all I know is that sometime when it’s a good day you won’t need a (third times a charm) Honda will start if she’s sick or healthy
This little engine works with the cylinder lying down and that's why it lubricates well! This engine is a war tank, changing the oil keto lasts a long time!
I don't think you will need a battery on them it should be like a push mower . If it's hard to see a spark providing it is safe no fuel close I sometimes use either just a little spray then see if I get a flame. From Perth Australia 26 may 2022
