35cc Honda on E85 query

[coln72]

Hi all,

I am currently running a gx35 Honda as one of the power sources on my 24hour racer trike. This engine seems to give the best comprimise between speed and economy as we only get 3 litres of fuel to use.

Next year (and this year if I choose to) I will be required to run on E85 fuel not normal unleaded. Now, I'd like to get a jump on the oppositio for next year and run E85 this year, but I have had trouble finding info on what exactly I need to do to the motor.

I realise that E85 is not as economical as normal unleaded and that it will "eat" some rubbers and gaskets, but what exactly needs to be changed? Is there a carby that can be modified to fit that is already suited to E85? I have access to a mill so I can skim the head to up the compression no problems and I am sure that I could up the timing to suit easy enough, but do you knowledgable guys and girls know how far I can go?

Hope you can be of asistance

Below are some pics of our vehicle to give you an idea on what I am doing.

My knowledge on this subject is very limited, so I will apologize now.
If you research alcohol racing setups, would that maybe point you the right way? I'm fairly sure special fuel line is used, and I think they drain the fuel system between uses. I believe there's a few guys around here that run alcohol, so be patient and somebody in the know should weigh in soon enough.

when they convert cars to bio diesel (similar?) they replace all the rubber products like seals and lines

i havnt heard about the gasket issue but im talking only from overhear conversations and breif disgusions

I am not an expert either, but have a look at THIS or THIS link. They have some info on what ethanol does to engines and carbs.
