Hi Ive been involved with the racv energy breakthrough RACV Energy Breakthrough
for a number of years, which is a 24 hour fuel economy race for kids. they get 3 liters of fuel and have to go for as far as they can in 24 hours. the cars generality use honda 4 stroke gx 25 or 35 cc engines and the odd 50 cc thrown in. they do about 700 kms the organises want to go to e85 Does anyone have any advice on converting these engines? I was going to advance the timing and maybe put a chainsaw carb on it, so the mixtures can be adjusted, also make a longer conrod to bump up the compression ratio.
anyone got any ideas?
