I have a 38” Husqvarna lawn tractor with a 18 1/2 HP B & S on it. When it is cold out side and I start it , the engine surges until it is warmed up. Then it runs smoothly. Is this normal ? Or should I be maintaining something ?

That is actually normal especially with the newer EPA mowers because they run too lean when they are cold.. I have seen several newer engines that won't even start below 50 degrees without outside assistance.
