You should be able to convert it back to gas, possibly a new carberator (all jets are bored out for alcohol), retard the timing and check the engines compression ratio, alcohol requires a higher CR between 12:1 to 15:1.

You may need to change the t-stat back to a cooler t-stat, alcohol vaporizes better in a hot manifold.

Hope this helps;

Randy
