Hi,

I'm just trying to fix up my mum's lawnmower - its a Honda "Buffalo" model.
Fairly new - but she's hardly used it.

She had problems with it ever since she got it - but only now has she asked
me to help - and the 1 year warranty has expired. lol.

It takes awhile to startup - a lot of pulls - but when it does it keeps on
going.

I checked the spark plug - the top end is black with soot. The air filter
seems fairly clean.

What's exactly the problem with it?
