As Dean mentioned, tiny adjustments is the key and using a weak thread lock to maintain that position is key. Also if you are using a second spring for a better first stage feel make sure it is a weak spring.

Yupper, I use Vibra-Tite but I cannot get to #2 with the safety engaging. I only have one place (hole) for a spring, I wind my own. Where does a second spring go?

I will have to find a picture for you a little later.
You mayhave the hidden screw in the trigger too far out too. That one pretty much set and forget.

Here's how I did mine--inline with what Healthservices did...averaging 1lb 12oz trigger pull and passed the slap/drop test. Before the spring was added, the gun would fire on the drop test. I shortened the safety spring so there's enough space to capture the added spring. I also drilled the sear so the added spring is captured there too. Also added a shim washer to sear pivot pin to take out the play. There was enough play that when cocked, the sear was not in line with the trigger and askew which resulted in varied trigger pulls. The shim washer took care of that.

OK... OK...
I'm seeing what you did there...
Thank you, off to the spare parts drawer, need me some springs.

You got it. Forgot to point out those areas. If you need the spring, I have a few and can send you one.

It is possible that you have to polish the shear a bit sand it smooth with finer and finer sand paper. Then hit with a polisher.
Then put a dab of good quality grease. I also replace the pins with harden chrome bits.
There is a lot of things you can do to reduce the pressure required to pull the trigger and keep the safety. This one happens to be a pp750, everything looks the same but different. Safety is to left, cocking to right.

I made a jig for the sear to polish them, the engagement area is really rough, just some 800 then 1000 grit paper on glass gives a nice break. I also make it 90°, the rounding causes creep, a clean break comes from a sharper angle.

Lots of good info on the Notos. Love it, but what about .177 and .25? Can’t find another cheap carbine as light in diff cal.that I like

I actually don't use my notos as much as my .177 pp750. I put the notos stock on my .177 and when I do shoot my notos I put the .177 tube and reg onto the notos so I can fire jsb rs pellets and get over 70 shots perfill. I don't need the notos .22 to fire so dang hot. Nor do I want it loud. I have too many guns that do that already. I just need it to be accurate lower power, but enough to take out the varmints, and shoot a lot of pellets.

Easy to do. Turn out the hammer spring, restack the belville washer stack for a lower pressure.

Although I was able to get under 2 lbs. trigger pull with just the screw adjustment, I did not feel it had enough sear engagement to be safe. It was very close to the shoulder radius of the hammer. I ended up machining the hammer to remove most of the radius also made the sear 90 deg. I then moved the 2nd stage screw closer to the fulcrum to increase mechanical advantage. This alone reduce the pull from 2# down to 1 lb. 7 oz. So about 30% reduction. I also took the safety detent spring out and replace with softer one to make it easier to engage. I am in the process of making a new lower assembly so I can use a Timney trigger for my Notos .25 cal build.

Anyone looking to adjust their Notos trigger, it is a 1.5mm
Make especially sure to verify the safety works after adjusting folks!

Some great info fellas ,Thanks 
. I might have to tear into mine soon.I adjusted mine but it’s far from great. First stage on mine takes some getting use to. There’s a little resistance to get it start, then it just goes.
