Does anybody know what size the jump starter is on these, I have been through all my hex keys and can't find anything that fits. It will be imperial I guess being American. It is bigger than 5mm but smaller than 5.5mm so it has me a little stumped. Another thing I have noticed is that it says no mix fuel and it has an oil filler point on it that says fill to this point. The colour of the oil in there tells me it looks like sump oil but I see no other reason to think it might be a 4 stroke
