Squiggle, who really must get his membership sorted again... but...
In our first time round, I can't remember from what point but late 60s early 70s, the (I think') Burmah in Mochdre was favoured and convenient from Pydew. Father had Austin 1100/1300s (Abbey company cars) and mother had an A30 and and A3. Big end went on the A30 coming back from Llanrwst (cricket - dad played for them) and it clattered noisily home.
I have served petrol, both in Craig Y Don and when I lived in kent and used the 2 stroke pumps. Bikes moved on to having their own tank for the oil and I guess (I don't know how it works off hand) mixing scheme. Other things like our strimmer, you just mix from a bottle. Plenty of new 2 strokes around but the demand for the "dispenser pump" that gave a shot to the right mix no longer exists.
Other comment perhaps of interest but maybe not... is that I once had a Lambretta that needed 16:1 . The strimmer is happy on 50:1
