Ok so the problem is i am having the hardest time getting my vavles out. i am going to seat and lap them (i think thats what its called) i took the vavle cover off on the side of the engine under the exchaust and carb ports and there was like a meat screen and know there is a silver metal plate with holes on the very right side of it where the metal spring is and i tried pulling it off but i just cant get it.
