Re: 2 questions
Remember the piston rings have pins in the groove to keep them from rotating when you put it back together. If you don't have a slant mounted plug in your head you could order one from Zoom that would be an easy fix. Maybe while it's apart you should think about changing all the studs with higher quality ones. Try getting it to idle with a little choke on. If it will then for sure you need to raise the needle by lowering the clip.
