qualcast petrol hedge trimmer

Hello all
i am new to the forum
I have a qualcast petrol hedge trimmer and the pull cord is hard to pull I have had the top of the trimmer off and the pull cord pulls ok I have had the spark plug out and it pulls ok I have had the trimmer on its end with the spark plug out and pulled the cord so if there was any left over fuel in the bore it would come out but it is just the same

thank you avb can you tell me how will i fix this (Sounds like the recoil assembly is binding under compression load.)
many thanks

My choice is Black + Decker. A machine is designed for decorative cutting of manicured hedges of medium size in width and height. However, if necessary, she can cope with long untouched bushes. Her knives are sharpened with a diamond tool and therefore even dry branches are easily cut. And in case of falling between the knives of some durable object, the protection will work, and the motor will simply turn off.
