Tuning How do your read the M3 Front Valve Adjustment Knob?

On the M3 I'm like a turn/turn and a half out from the last line. That's also how FX sent my M3 back to me after they fixed the front reg.

Good question! I have been going with the 4 lines and counting the grooved lines as lines. I have the M3 in .35 and the M2 and both have the exact same number of lines. I saw on the manual the 6 lines on certain versions but have yet to see one M3 with 6 distinct lines/grooves...
I just went by the lines but now you have me thinking what if I was wrong and your second photo was/is correct...again, great question!!

To be more specific, I count line 6 in your 2nd diagram as my last line then 1.5 turns out from that is max open on the valve. You'll see a healthy fps increase

The grooves are the indications. So 1.5 turns past the fourth groove is six. There may be a six groove version in the future.

Yeah, I could never make sense of that instruction. For a given second reg pressure and max hammer spring I backed it out until I didn't get any more velocity and then back in a touch. Then I used a caliper to measure the distance (9.4 mm@130 bar). My M3 is very sensitive to the position of the valve adjuster. So, just eyeballing it would not provide consistent tuning. It's also in a spot where you can move it accidentally, so easy enough to reset with the caliper.

You read your front valve adjustment knob with a pair of digital calipers guys. That thing only needs two lines on it. One for fully open and one for fully closed.

You just blew my mind..If setting 5.5 turns out to be 5.5mm from closed...you are going to be a hero. Good thinking!!!
