Alright on my big bad 82 DS 50. It will sputter out and when I take the plug out the the hook is bent in to the other queery. I bent it back out and put it in numerous time sit keeps bending it andsputtering out again. I am thinking its a Carbon build up but I don`t feel like takingapart the top End because I don`t want to make a new gasket for it. what do you guys think.
