    i am having a ***** of a time getting the cam follower and cam to line up correctly. call me ignorant, but it seems like the instructions in the manual leave quite a bit out. maybe i am overthinking this. anyhow, the idle speed screw is out of whack, the throttle cam is out of whack, and the...
