I rebuilt it with newer materials, not the nos stuff. So worst case scenario if fuel got in the crankcase? Should I drain the oil? Will the oil separate like water from the oil, or just all new oil. I put an electric fuel pump on and that's working, but now I burnt out my ground cut off switch for some reason. I used this 4 ga wire for the ground, but it consisted of a lot of thin copper wires. I feel like trying to start it so much is making it too hot on this type of wire. I'm going to try a new thicker wire and see if that works. Any idea on why that ground wire is getting so hot?
