Flashback Arrestor

Flashbacks have been a concern for all of us. Carbureted engines are notorious for it. However, fuel injected engines rarely every experience a flashback. Backing Soda stops up flash arrestors. Bronze Wool flash arrestors eventually stops up because the electrolyte eventually sticks to it; same with porous arrestors. Some of the time, check valves work, but not all of the time.
