Burnham have been in good form themselves of late, but were no match for hosts Chard – particularly Butcher, who now has 10 goals in two games.
A short corner strike gave them the ideal start, and it was 5-1 at half time.
Three more goals in the second period wrapped up a victory that was as emphatic as it was important.
This latest success followed wins over ECVH (4-2) and league leaders Taunton Vale 3rds (4-3), which see Chard sitting on 13 points.
They are second bottom in the table still, as Taunton Vale 4ths beat Minehead on Saturday to stay three points ahead with a far superior goal difference, with Winscombe 2nds two points up on Chard.
Therefore Chard (goal difference of -25) must win this Saturday, away to bottom side White Eagles 2nds, and hope that Winscombe (-22 goal difference) pick up no more than one point from their remaining two games, away to Burnham (March 25) and at home to ECVH (April 1), if they are to secure survival.
