Also, what's your valve adjustment technique? Are you adjusting them on a cold motor that has sat overnight? What specs are you adjusting them to? I would await your response before you buy anything.

They've been adjusted cold in the past. And I'm doing .04mm - .06mm on both intake and exhaust. However I've seen other people on this form say Intake: 0.05 mm, Exhaust: 0.08 mm. When my valves are in spec it runs great but the gap is far too wide everytime it stops running well. I'll try and get some pics of the engine tonight to make sure of the model. Anything specific to look for on the motor to help indicate the year and model?
