Spark plug for a Sabre 2045 Petrol Strimmer?

Hi,

My Sabre 2045 Petrol Strimmer fell over and the spark plug broke, it is a tiny thing. I can't source a replacement at B&Q or any motorcycle shop.

Where can on be obtained please....


Please be quick, my neighbours are stsrting to moan about my garden being un-tamed !
