Ethanol has a higher octane rating than petrol, it burns cooler and completely, as it is an 'oxygenate' (the fuel contains oxygen molecules.). It also has a lower energy content, around 30% less than petrol, and it should make an engine run more smoothly, but slower and do fewer mpg.
Good for destroying rubber components in the fuel system, especially old bikes!
Ethanol is cheaper to produce than petrol, but we never see reduce prices at the pump!

With taps and dies, you get what you pay for. Go for known brands like Warrior, Presto, etc. They must be HSS, and slpit diesso you can 'fernurgle' a thread as required, Buy as you require or you will be paying for tools you don't use (trust me, I have tools people have never even heard of). Over the years my collection of t's & d's include metric course, up tp 25mm, many metric fine up to 26mm, bsf, bsp, whitworth, unc, unf, ba, and a full set of Venezuelan Beaver's Trap thread! (and many specials,some l/hand thread). Yup, a man can't live without taps and dies!

Well, there's a blast from the present!
I have one of these which I have used on/off for about 45 years. I say 'a blast from the present', because i used this to test some mini cooper (new type) coils. Indeed, the machine did its business (after I repaired the multivibrator) and as such, it was a perfect demonstration for my students.
Thems wos the days, all yer needed wos a set of feeler gauges an' a 'ammer! :
