CCM J12 tuning question

What are the ways to tune this marker. My gun today was shooting all over the place velocity wise.

What is the reg screw suppose to be set at. Once I get that set I will work on velocity next. But I have it somewhat flush and it was still shooting all over but at least its below 290 and above 260

Hmm.
A few things need to be done.

What is the paint sized at? Are you sizing to match, or under boring?

Have you messed with the reg adjustment?

Have you messed with the rear IVG adjustment?

Do you have the reg tester for the J12?

Personally, you shouldn't have needed to mess with the reg screw. It's set from factory and I doubt it had walked on you.

I know my J12 when I had it, the screw wasn't flush. I guess what you could do is sweet spot the reg and marker the old fashion way. Bottom out the reg and go from there.

Tested 3 J12's. The regs were set at 275 from the factory. Shouldn't have to mess with the regulator at all. Just the IVG.

Paint size will give the results you have posted. I shot Marbs today, 681-686. My velocity was 270-290ish. I shot some Valken @ SPE and the velocity was really tight, but the paint was fairly consistent in size.

I had the same troubles with mine, twice.
It was a valve spring seat issue (I'm not sure of my vocabulary: I'm talking about the round part which is inserted inside the guide rod and that keep the valve spring in place). This part felt down so the spring wasn't doing it's job (the valve was closing with pressure only, explaining erratic velocities).

Take a look at the valve assembly: if the valve pin doesn't pop outside the valve body, the spring is not in the right place anymore.

I was shooting marbs in a 684. 687 was too lose and the paint would roll out but I had a better shot pattern and paint flight.

The reg was adjusted bc I'm use to egos and geos and forgot about the ivg. So the reg isnt set. No reg tester. If someone is in MN I would love to get this fix. Otherwise it'll be the bottom out way which I need to be explained

Allblack. Do you mean the black or brass portion of the Valve pin?

Or Ghostleader, can you tell us if you have ever disassembled your marker's valve assembly since receiving it from CCM?

TF: I mean the other end of the valve spring. There is a kind of washer which mounted on the inside of the pump guide.
By the way I've glued this washer to the guide (obviously this is NOT an official CCM fix ) and I didn't get any trouble since.
I get post a picture to explain if my vocabulary is that crap
