Two goals in three minutes put Sevenoaks Town top of the Southern Counties East League Premier Division at Jockey Farm on Saturday.
Mark Jones netted his first league goal for Town to give them a 13th minute lead, before Byron Walker and Rory Hill completed an early season double over the newly promoted Tunbridge Wells villagers.
Walker saw his early effort blocked by keeper Joe Cullip before new signing Jones made it two in two games, touching home from close range - his first goal for the club.
However his afternoon ended early - limping off with an ankle injury 10 minutes into the second half.
Brett Ince, playing again in a new midfield role hit one effort wide, before blasting over the bar.
Tempers flared when Town old boy Danny Powell left skipper Corey Holder on the ground after a wild kick, but escaped unpunished.
Town conceded three quick corners, but survived Rusthall's pressure to maintain the lead at half time.
They missed two chances to score a second soon after the restart through defender Tom Ripley and Jones, before Carnegie saw his effort held by home keeper Joe Cullip.
He then pushed substitute Tom Youngs' shot into a post for a corner, before the same player went close again and Walker fired over.
The striker then doubled the lead after 77 minutes, converting a poor back pass, before Hill got the third three minutes later. Jason Thompson picked out fellow substitute Youngs with a perfect cross field pass, beating his marker before crossing for Hill to head home.
The victory took Town top on goal difference from Croydon and Lordswood with games in hand on both clubs.
