ive been suffering slight hesitaion every now and again and not really figured out the problem!

however i changed the rocker cover gasket and noticed this

it looks like its been arking out to me.....

and since i put it back together im getting a uneven idle and a slight loss of power... anyone recon its the coils at fault?

any tips would be great
