strange start

[max]

In NZ we only have one brand that contains ethanol as far as i'm aware, just googled "ethanol water content" and came up with some surprising facts i did not know about, lots of info on the net, some good some just made up, i just extracted the ones that looked reliable.

Ethanol works different in two stroke engines, the ethanol ( alcohol) in the mixture does not mix with the lube oil in the mix, here is a husquvarna site with more info;

Ethanol can be useful to remove water from fuel tanks with vigorous mixing and instant removal, the water content mixes with the fuel, suspending in it and settling to the bottom OVER TIME (where the fuel pump lives).
Here's a guy testing mixing additives to gas and the varying disappointing results ;

And a way to extract ethanol from the fuel, no ethanol in aircraft engines, wonder why?

Actually i have trouble believing the ethanol content in that fuel and they don't show the extraction content but it shows the principle very clearly.

As for pdedse's delayed start i don't know if this is the problem but maybe worth considering for the lack of another solution, i also had an instance of a crank fine but no engine start, i tried various throttle positions and after some time it just fired up, all cylinders at the same time, no hesitation, it only happened once that i can recall and was not related to ethanol, i don't use e-fuel.
