You have to adjust the trigger in the correct sequence or youll never get it.

If you look at the safety right above screw d you'll see a line where the trigger group rotates slightly around the safety so first back out screw b so it has no tension on the 1st stage spring above then you’ll have to find a balance between a and e you’ll want to screw a in to take more weight off 1st stage spring then you have to fiddle withe& f to gst things right. Its kind of a pain but i hope i stated this right so you understand.

Thank you @Solo1 After reading and studying the photo a few times, I got it! Now, I just need to know how much to cut off SPG.

A little bit at a time, lol. Start at maybe a half coil at a time, put it back together and see what you think of the trigger. Go too far and you create a big problem for yourself.

Can I cut without removing the brass part?

Can I cut without removing the brass part?

Yes. That brass part CAN be unthreaded but mine had a bunch of serious loktite and required a lot of heat. And you don't want to bugger it up. Brass is typically soft. And then if you get it off safely you've got to get it back on with just the right amount of threads engaged nearly identical to what it was before. In my opinion, the easier/safer route is to cut coils with the brass eared piece in place. Wire cutters or even a cutoff wheel on a Dremel (CAREFULLY). Don't cut anything but the half a coil you want to cut.

 

[EDventure Outdoors]

Half of coil isn't much but I understand the idea of not going crazy.

 

[Franklink]

It'll likely be multiple half coils to get where you want. I'm being very conservative in my recommendation here b/c you simply can't put it back if you cut too far.

I want to say mine was 2 or 3 full coils but it's been almost a year since I did it so I don't remember very clearly.

 

[Franklink]

Im pretty sure I used this type of wire cutters. Not the exact one but this variety, just some old ones in my tool box.

Someone should create a shorter spring kit with mini-plastic spacers to adjust the spring rate. This would allow you to experiment.

Not a bad idea.

I'm thinking I'll make a how-to post on fixing the trigger. The Ghost trigger fix comes up pretty often but it's often embedded in other Ghost discussion. Maybe a free standing post, titled appropriately, will be easier to find for Ghost owners.

Well in that kit i posted there is a lighter spring that works fine, but thrn like cole said you have to take that yoke off and that adds a whole other dimension of adjustment to get right. The spring i used was a .4x5x30 mm stock might have been .5x5x30 mm

Exactly how this has progressed.

As long as people are being helpful, I'm ok with it. I just was in agreement that it makes it hard to find.

Look im not an airgun tuning expert but have some experience. From my experience with 2 mavericks and an m3 and with a redwolf and 2 reveres and now 2 ghosts i do have some knowledge. I see too many people adjusting regs too much and then wonder why they have problems with them. So anymore i try to keep it simple. When i first got my ghost 177 hp i thought I would need a low reg pressure cause i planned to shoot it at less than mfg lowest speeds. It shot very well with 80 bar @ 810 to give me under 20 fpe so i shot it that way all summer and it was great! Now i wanted to turn things up and try slugs turnd up the reg to 140 ( daystate seems to set up their guns at this reg pressure note the 2 reveres are set to this pressure) and what do you know it shot the same as 80 bar, now this is with what they call the med hammer spring not the stock heavy. Had a low sd in both settings which I don’t quite understand but thats the way it goes. So my recomendation is to decide what ammo you intend to use if only 1 kind then set reg between 130-150 and find a velocity you and your projectile like and a low sd and leave it. If 2 projectiles find a setting that will suit with just wheel adjustments and leave it. Thats how im doing the 177 and my 25 oh almost forgot have nearly the same numder of shots with 80 bar as 130 and the latter might actually be a bit better?

The 130 bar *plenum has ~130/80 more air in it than the 80 bar plenum. Also 130 bar has more pressure energy, so it takes less air to get the pellet to your desired velocity, that air also flows into the barrel faster, and the valve has to open/travel less so from the time the trigger breaks to the pellet leaving the barrel should be shorter.
*I haven’t found the plenum volume stated anywhere.
I asked Daystate (again) what they designed as the optimal regulator set pressure range, and if there is an upper limit that they recommend not going above.
