There is a bur in the head keeping the bolts from turning. Drill the top of the bolt off and after you remove the head just unsrew the stud sticking up by hand. The bur will be gone after you drill it. I had to drill all 4. Sound like you only have to drill one.

I remember that phone call. That was classic

Hum the reason why i ask is because I'm having problems with my spare reedy. It will fire up after a while but I have to hold the gas because she wont idle. and when she does get going it sound like the the low end is groggy so i started to work on that needle first and than the top but still no luck with the idle any suggestions?
