PHILADELPHIA -- The Los Angeles Kings improved their play after blowing a two-goal lead on the road. A little experience goes a long way.
Matt Read and Jakub Voracek had Philadelphia's goals. The Flyers had won five in a row, but they dropped to 12-3-1 in their last 16 games while falling to third place in the Metropolitan Division, one point behind the Rangers.
Los Angeles had a 2-0 lead entering the final period, but Philadelphia tied it at 2 before King's winning score with 9:24 remaining.
"We've been a team that's played together for a lot of years and have been through a lot, so we're a mentally strong team," Kings center Mike Richards said. "We can battle back after that."
The winning goal started with a Flyers turnover just outside their zone. Slava Voynov raced down the right side, creating a 2-on-1 with King. King took Voynov's perfectly placed cross-ice pass and beat Ray Emery high on the stick side on a forehand from close range.
"It settled our game back to where it needed to be and pushed their game down a level," Kings captain Dustin Brown said.
Carter opened the scoring 1:49 into the second period with a wrist shot from the left circle. Alec Martinez took the initial shot from the point, and it deflected off the skate of defenseman Mark Streit and right to Carter.
It looked as if Vincent Lecavalier had tied it a minute later, but his shot to a wide-open net went off the right post, then the crossbar and finally the left post. The goal light went on and the arena horn blared signaling a goal, but officials never stopped play. The officials' no-goal ruling was later upheld by replay.
Williams then scored with 2:31 remaining in the period when he finished a backhander after Emery gave up a bad rebound.
The Kings also had a goal disallowed in the period when Martinez's apparent tally was waved off because Carter cross-checked Kimmo Timonen in front of Emery just prior to Martinez's shot.
Los Angeles dominated the period, outshooting Philadelphia 20-9.
Philadelphia pulled within a goal just 29 seconds into the third period when Read was credited for a score when the puck deflected off the skate of defenseman Jake Muzzin.
Voracek provided the equalizer with 11:42 remaining in the third period when he deflected home Scott Hartnell's shot from the point after the Kings turned it over in their zone.
But King's goal was too much for Philadelphia to overcome.
"We played a good road game," Kings coach Darryl Sutter said. "We need the points, just like they do. We knew were coming into a tough place and we played good. We're just trying to make the playoffs."
So are the Flyers, who are at the Rangers on Wednesday. Coach Craig Berube will be looking for a better effort than he saw in the opening two periods against the Kings.
"For the first 40 minutes, we didn't compete hard enough," Berube said. "We let them outwork us. That was the difference in the game."
Emery started in place of Steve Mason. It was just the third start and fourth appearance for Emery in the last 18 games. Emery was sidelined for five of those games with a lower body injury suffered Feb. 27 against San Jose. He finished with 38 saves.
Jonathan Quick made 30 saves for Los Angeles.
Carter and Richards, both former Flyers, were booed every time they touched the puck in the first period. The duo, who helped the Kings win the Stanley Cup in 2012, were traded after the 2011 season. Carter was playing against his former club in Philadelphia for the first time. Williams also is a former Flyer.
