What happened to Elmer? Want to make sure you get fixed up, but while we're waiting on your answers to several post above, I'm still struggling with a little bit of carbon (and thus decrease in volume which increases pressure) increasing cylinder pressure enough to cause premature ignition and backfiring while intake valves are open (ie through carb).

You guys are the experts, but it seems to me that if that could happen, why wouldn't the engineers just increase compression ratio on these gasoline engines and get rid of plugs, and ignition system? How do we know that actually happens?
