2-Stroke mixture

If it's like mine 50:1 will make it smoke like a pig, even though that is the recommendation.
I'm guessing that when they say maximum they mean don't load it with more oil than that.
 
We have a very handy mixing bottle for the garden equipment, from a garden centre machinery section funnily enough; it has a scale on the side so one can make any mix one wants; I'd use 35:1 ( though that seems a strange figure ) otherwise if it goes pop that'll be an excuse not to honour guarantees.

I don't know - seems fairly clear to me. It is the fuel/oil ratio, so it shouldn't be more than 35:1 (i.e. 50:1 would be no good), implying that a ratio equal to or less that this is OK (i.e. 25:1 is fine).

That is logical.

Using more oil than a specified mix would normally do no harm. Might smoke a bit (more than Lakey) and in extreme would foul the plug but do no permanent damage. Common to use double the normal quantity during the break in period anyway.

Too little oil could lead to serious engine damage or seizure during storage.

Ah, but isn't it equally likely to mean "Use at most 1 part in 36 oil" so that 1 part in 51 would be fine but 1 part in 25 would be too much?

It all depends on whether you think 100:1 is a high ratio or a low amount of oil ... and that's the ambiguity.
 
Given that these ratios are always something:1 I think it's obvious what they meant even if the wording is ambiguous. They almost certainly don't mean 35:2 would be an alternative but then this was probably written by an intern on minimum wage as the single qualified person was busy designing the next device, or made redundant...
 
We had a Suzuki outboard, the instructions for which were (I think) 100 : 1, but 50 : 1 if used commercially. (can't remember the exact numbers, but it did imply that if it was going to be worked hard, it was best to put MORE oil in, rater than less).
 
Hello Nigel
I have been told that air cooled 2 stroke engines run at a much higher temp than water cooled outboards so need a different knid of oil for the petrol. So you need an oil for garden machinery ie chain saws and not the outboard oil. Having said that I just shoved in some o/b oil into my line trimmer and so far OK. Amazing little engine and so cheap I wonder how I can fit a propeller to it? olewill
