The problem with nitrous is that it adds more oxygen into the combustion chamber. You need to have the proper amount of fuel going in too or it will severely lean out! You would have to run it pig fat rich all the time to compensate for the extra air introduced with the nitrous. Modern cars with electronic fuel injection can compensate with increased fuel pressure adjusted by the O2 sensor. Carbureted cars had two lines running to the plate, one for fuel and one for nitrous. Run lean and blow it up!
I'm currently dealing with an issue with an engine I'd shipped to Florida... leaked supposedly gas so the USPS has it in Federal Way, Washington,awaiting me to contact them and figure out what to do. Unless there was a tiny amount of fuel in its carburetor, I'm at a loss. It had no oil in it and no gas tank, so that's the only thing I could figure.
