Like others have said, they are problematic and I had one 10 years. Washers going, generator blocking, leading to seepage running down the reservoir and catching fire. I once finished up having to boot the bar Steward into the lake in the dark for fear of thing blowing up
I must have gone through 20 generators over the 10 years and it was a relief when it died a death.
I now have a Primus Eta Power multi fuel, not cheap, but it burns anything that's liquid and flammable!
Here's the list Ive burnt in it
Petrol
Paraffin
Gas
Meths
Diesel
Veg oil, bit hard to get it going though
Turps
White spirit
It should be noted only the top 3 are listed by the makers for use.
