@NMKawierider and everyone.
I have some hard starting issues when cold and some chattering/ metallic pinging from the front cylinder, i can hear it with the old "stethoscope" long screwdriver trick, it comes from the head (disappears when it heats up), back cylinder is silent.
What's the proper way to adjust the valves?
When at compression tdc the rocker arms have some play, they wiggle. Are you supposed to lift/pull up the rocker arms and then insert the feeler?
Some say that when you insert the feeler gauge, the rocker arm will raise to its maximum point towards the cam.
I found that NOT to be the case, first time i did the valves i didn't pull on the rocker arms, i just inserted the feeler gauge and adjusted until it was catching. After reassembly the valvetrain was noisy.
When i repeated the process i pulled on the arm and this time the feeler gauge slid out without catching, so there is definitely a difference.
So what's the proper way?
Bonus: how the heck do i go about doing the front cylinder? I can't see the exhaust valves (especially the left one), i go by feel only (i have a feeling that's why the front cylinder is acting up). Any tricks?
