I have just run the generator now for 20 mins with no smoke evident.
The only thing I have noticed is that I dont think it holds 750ml as displayed on sticker. I estimate I only put 650 ml in and then I lost a bit when it spurted from oil fill plug yesterday because I tried to check immediately after stopping.
Now, I waited 1 hour and oil level is just below overflow point but clearly visible.
If this generator is not regularly used, how often should I run it to keep it in good condition ?
Very strange problem - thanks to all of the members who responded.
