The Scottish winger had been struggling to find the form that saw him win a host of accolades at last season's Player of the Year awards, including the top prize.
But Burke was back to his best against the Robins, in a game in which he also scored.
"His was a complete performance in terms of everything he did," said Clark. "He made numerous chances for other players and numerous chances for himself. He also scored a great goal and he won us the penalty. He was in very good form and I hope that will kick-start his season, because certainly him being in that form for the remainder of the season will be a massive benefit for us."
Clark admits Burke's early season showings were a bit of mystery because he knows what a talent Burke is and how hard he trains.
"I can’t put my finger on it," he said. "It’s been a frustrating thing for me because I love wide players that go at full-backs and take them on and be positive - make goals and score goals. And Chris fits that bill. It’s been more frustrating because I know how desperate the lad is to do well and how hard he works at his game.
Burke's team-mate Marlon King was also delighted to see Burke back terrorising defences.
"I talked to Burkey and I said to him just to do what you did last season," said King. "It’s all about confidence. You can see he hasn’t been himself and he needed that on Tuesday and it felt nice for me to set him up.
"He had one chance in the first half and it hit the goalkeeper and he probably thought it’s not going to be my season. But he’s slipped and one’s gone in and that can be what you need to change your season. Hopefully he can kick on because he’s an excellent player and that’s why he cleaned up in all the awards last season."
