The correct AFR for alcohol (ethanol) is around 8 to 1 versus gasoline at 14.7
to 1. Switching to 10% ethanol should equate to about a 5% richer mixture.
Ethanol produces more power than gasoline ? hence alcohol race engines but much
more fuel required. Your mileage will suffer.

The issues with the Ethanol will depend on the percentage of Ethanol they will
be putting in. Here in California most of the Ethanol is 10%. However they are
talking about raising that and if they do we will start having real problems.
The most common issues we run into are . Overheating and miss fires under heavy
load due to lean mixtures. Especially worse on the Tri Carb.
This can usually be cured by installing the Rich needles.
The other issues are lack of power and lower gas mileage.

It seems that the UK is to be blessed with this stuff. I?ve been asked for my
thoughts on the topic and, as I know nothing about it, I?m looking for advice.
See attached.
What are your experiences? And what are the ?dos and don?ts??
Thanks,
Simon
