In over my head... already. Compression suddenly lower?
So when I first got my rig I did a compression test on all the cylinders of the 2F. All were around 145psi except for #2 which was about 120psi. After much advice gathered from this forum I decided to adjust the valves. So I just completed my first valve job and now I'm confused. For reference I went the service manual route, heated up the engine (it was pretty warm in there) and found TDC. Adjusted 1 2 3 5 7 9 rotated the flywheel 360 and then did the others. Everything seemed to be the correct clearance.
Now for the sanity check:
Checked the compression afterwards and it seems like #2 now has about the same compression number as the other cylinders... BUT.... now they are ALL around 120psi.
Just to make sure I didn't make a colossal goof. Valve 1 is exhaust, 2 and 3, intake, 4 and 5 exhaust, 6 and 7 intake, 8 and 9 exhaust, 10 and 11 intake, and 12 exhaust. Please tell me I'm at least correct on that part.
So, did I screw up the timing or completely blow the valve job? This is my first 40 so I don't know what the engine should sound like when running well. It sounds good to me, but I could easily be missing something horrendous.
Thanks man.
Peace
