Did you change the timing of the spark and valve timing for alcohol?
Because alcohol has different timing to benzine/gasoline...
I remeber running alcohol in my car, had to use bigger carbie jets, change the mixture setting fpr the high speed and low speed settings and change the spark timing.
If the compression is to high for the valve springs you will get blow back and pre-ignition in the intake and exhaust manifolds. This usually results in overheating. And wasted heat is no good.
Sorry to go on. But yeah- timing changes for alcohol engines anyone?
