I build engine-powered models. My experience is that some cya glues
dissolve in petro products. That's why we fuel proof the areas that may
come in contact with the fuel/oil. This is true for both gas and alky
burners. All the MG engines I've torn down had oil on the back of the
thrust washers. How many miles did that engine last?
