g'day im 15 and iv got a villiers engine of wich i dont know what model or hp it is but i think its around 5 hp. i can send a picture. it has a cowling which goes round the side over half the cylinder head. i cant get it to fire though its got a beautiful spark and everything seems in perfect order. iv stripped and put it back together with new gaskets and everything i put ether in the cylinder and i tried everything i can think of. the piston is flat. if anyone can i help on how i can get it to run or what kind it is i would be very happy. thanks
