I'm thinking if the carb was for alc, as in gaskets, orings etc, and the fuel lines were the proper ones and the pump wouldn't be eaten up maybe a
small amount could be poss. They mix nitro with alc for a reason. I never
tried it myself, the racing gas cost enough and I didn't want to ruin my stuff.
I just had a friend that used to put some nitro in his Chevy at the Drags,
and I didn't think it was worth the headache.
