WOW! Talk about the confusing. Timing is the key here. To adjust valves put each cylinder at TDC on the comp stroke and adjust each one according to firing order, vac valve pointing toward #4 and rotor pointing to #1 @ TDC on #1 comp stroke its that simple. STOP _THINK _DO...Look at all the threads over the past few weeks... If you feel like you are chasing your tail you probably are(speaking from experience).If you did it right then a component let you down. Which one is newest or oldest or modified from before?
