I have the classic buzzing, and stalling, and loss of power at inopportune times. I hit up the archives and could make a case for many things to check, which I will do in the morning. My hope is that someone will give me a sequence of places to check so that I can make good use of my day off, like maybe a fixed gear bike ride or something fun! I read one post that said there is something near the rear of the valve cover, on the fire wall? Thanks for any help you can give!
