HHO Gas EP-350 Machine Running a 5.5 Honda Engine

I pushed the HHO Gas button on the machine and the machine goes through quick computer calculation and then start making the production of HHO Gas on demand. There is a delay when I first push the gas button giving me time to pull start the 5.5 Honda engine. Nothing has been changed on the advanced timing all. We are running stock timing as is from the factory.
