A couple of years back, I started running the P6B with increasing amounts
of ethanol.  I got it up to 80% ethanol without any difficulty.  Timing was
left unchnged at 2 deg btdc, which ws the most I could get wy with with our
brillint "lead replcement petrol"  I hd to mess round with the mixtures
progressively.  At 80%, performance was down  bit and consumption was up a
bit, but still in a range I could live with.  I have no doubt I could have
restored the performance with further profound fiddlng with the carbs.

I stopped for two reasons.  The nearest source of ethanol was 100 miles
away on the other side of Sydney and I elicited zero interest from the
motoring orgnisations, the biofuels organisations, politicians of either
water or the press.
