Hi Team 

My Atco is having problems, (mainly with me I think) it runs for about 3 /5 mins, then stops, and smoke comes out of the exhaust box.

So I have bought new spark plug and oil.....   

The petrol is new. it has not been sitting in a can for 2 years.. 

and I also seam to have a leak..

 

I should go out and get a hover, but where would the fun in that be....

 

Thanks for reading ..

First slacken the fuel fill cap and see how you get on. Could be a blocked tank cap breather causing the tank to vacuum.

Second, what colour is the smoke, white or black?

OK, suggest that you go ahead with the loosened tank cap. If it has been running with the plug  in your first image there are no signs of oiling , in fact it looks very clean and may suggest a weak mixture which goes with the possibility of fuel starvation caused by restricted flow from the tank.
