That engine looks like it was run on straight petrol.With no oil,I find that a lot.I guess due to the fact there is so many four strokes out there people forget that there two strokes need oil in its fuel.Especially as you just can't go to a servo and buy already mixed two stroke.Remember that everyone or am I showing my age?
If it was my mower I'd just use it for spares,but in your case you said you have a hard-rubbish collection coming up,so I'd hang onto it and do the drive around.You might get lucky and be able to make one mower from two.
As far as your questions go.The only silly question is the un-asked question.So no need to apologize after all it is the best way to learn with the help of people who have the knowledge.
Just keep having fun with the two strokes I prefer them over four strokes.
