I have a Sheen X-100 (or now known as a X-300) that is perhaps 50 years old. I have a motorbike, go-kart (my 14 yo son...), 4x mowers and therefore with a little kerosene and lots of oil changes, never run out of fuel! You can buy them on eBay nearly new. They are not designed for snowflakes or the woke generation! A little like taming my own dragon.
