Our story thus far-
Carbs are off. Plugs are out. Valve covers are off. Compression results: #1: 110 psi #2: 130 psi #3 121 psi #4 125 psi This was AFTER I did a really thorough valve job going around and around to each valve until I was sure they were all 1/2 to 2/3 turn past contact. hmmmm. I studied the orientation of the screw slots on #2. Exhaust about 3:00 oclock, Intake at about 1:30. I reset # 3 screws to more closely duplicate this - required maybe 1/4 to 1/2 turn. Retested compression. Now it was 128 psi. Long story short: I've readjusted the valves again to achieve the highest compression. Didn't increase or decrease any setting more than 1/2 turn one way or the other. #1: still messing with it #2: 130 psi #3 128 psi #4 130 psi This seems like a really optimum setting. -OR- Iz this REALLY STUPID? uh, could be. Opinions? Experiences? Mild interest? Speak to me. (this post edited to correct porely remembered results- #1 especially) Attached thumbnail(s)
