If this prevents spark plug fowling as claimed it will be great and brings back a fond memory. During the Sydney Olympics in 2000 I flew a Piper Warrier over the Hawksbury River north of Sydney and the engine started missing - quite possibly due to this issue. A bit of a nervous prospect as there is basically nowhere to land there. At the time there was a huge air exclusion zone over the Olympic Park and there was excited talk of how quickly jets would be dispatched to shoot you down if you violated the airspace. Anyway, the moment we reported engine trouble we were given clearance to head straight back to Bankstown - pretty much right over the top of the games. Good times!
