cam timing is perfect according to the pics from shawn and the fsm pic that was posted. distributor points to #1 and crank is at tdc. HOWEVER, it idles beautifully and starts up just as good, the problem is, revving up. its slow and unenthusiastic. ??!! i cant explain it. i just ran it a couple seconds again just now with the valve cover off and then checked all marks again. no dice. everything still lines up. no missing either... what now?
