bio ethanol

Hello,
Has anybody have an experience with bio ethanol in a dauntless?

but is there any risk to burn the valves by using bio ethanol?
in Europe we have bio ethanol E85.
It is ethanol whith 15 % of super 95 unleaded.

 

From quickly reading that article, it seems to me the main problem with a carburetor is the mixture. The author recommended drilling out the jets to get a richer mixture for the less energetic alcohol. Most modern cars are fuel injected, and will automatically adjust the fuel mixture based on the operating conditions and amount of residual oxygen in the exhaust. Carbureted cars aren't so sophisticated...

I'd think, if anything, the E85 will be a less energetic fuel and there will be less danger of burning the valves if you set the mixture correctly. I expect that if you run E85 and don't adjust the mixture, combustion will be very lean and you'll be in danger of burning the valves. A low float bowl level (due to the less dense E85) will also make the engine run leaner.

That article had a surprising lack of any comments about compatibility of materials and such (maybe I missed it?). IIRC it's the biodiesel that will dissolve rubber hose, not E85?

Here in the USA (at least in MA), pump gas contains as much as 15% alcohol, and it does not seem to affect the cars. I'd follow the suggestions of the article and rebuild your carburetor with a newly made carburetor kit (not some 30 YO kit). I'd also use all chemical grade clear tubing (tygon) for the fuel. Rubber hose may be ok, but I'd worry.

 

in Europe also there is a % of alcohol in the super95
