Drat! That last one should have been in "What did you do ….."
On the subject of fuels, which we are, sort of: I have been fairly casual about the debate about old fuel. But the Cambridge doesn't get used much, and I drain year old fuel out and put a bit of new in, if it is that long between runs.
I decided to try the old fuel, by now probably 18 months old, in the lawnmower. Lawnmower has been tolerant up to now, not minding if it is running on two stroke left over from the outboard, for instance.
With the old fuel from "Alice" the mower was firing every other stroke or so, and eventually stopped. It has a suction operated fuel pump, and I think the erratic running has blown the seals in it, because now the engine appears to be ingesting fuel directly from the tank, bypassing the carb.
Fortunately it is convertible to gravity feed, but I will be a little more careful using old fuel from now on.
