Dont give up so fast your not burning that much fuel because you jets are to big, which they probably are. Using that much fuel, means its going past your needle sets.
1. Are your needle sets titanium? They need to be for alcohol.
2. What is your regulator pressure set at? Needs to be less that 7.5.
3. If you have a big fuel pump it may be pushing past your regulator.
You need a good regulator for a high flow fuel pump or you'll get whats called creep. Thats where your fuel pressure gradually creeps up until it overruns your needle set. Check these three things before you give up on alcohol.
Good luck,
Dean
