I wish I could get that many runs on one plug with my 24.7. That stupid thing has so much compression that I'm changing a plug every 15 tanks or so.

What does the plug look like when it dies? My plugs are hit or miss depending on the tune of the engine. Too lean or too rich is a sure fire way to kill a plug. I've had a plugs last a half gallon of fuel, while another last only half a tank.
