This is correct. Run it hard na parang may LBM ka, it will flush out carbon deposits sa valves and seats, clear sludges sa fuel lines and cough out the soot build up sa muffler. Do it time to time because carbon deposit will solidify like cement, parang brownies na naiwanan ng matagal sa oven.
Lagay ka na rin the hose with water sa tambucho para malusaw ng kaunti ang soot before you run it hard.
