LTS UK Rotavator

Hi
We have been given a second hand LTS UK rotavator (STV 130 ...4.0 HP) but the plastic throttle cable trigger/handle has broken..the part that holds the cable...does anyone have any idea who supplies spare parts for this make...I have a feeling its branded under diff names as I`ve seen a new one made by Fox that looks like ours...can anyone help please
Cheers Paul
PS I have contacted LTS but have received no reply !!!!!
