Karnivor pressure tuning help

Ok so Im not the greatest when it comes to tuning autocockers but i can get it pretty close. Right now im having a little bit of trouble getting my karni shoot sweet again.

It seems the lower i make the reg pressure the higher the velocity goes, and what's even more strange the lower i make the pressure the better it seems to shoot at faster speeds. I have to have the tickler lpr all the way up to not get any shootdown. Here's my dilemma, when i go down to low the cocking solenoid starts to leak from the gasket.

my friend has my chrono so i dont know what its shooting at just yet. But i know it's shooting paint all screwy. Could be to small of a bore but yeah.

What do you guys suggest?
My karni is pretty much stock early run. I put an MP4 ram and a yakuza board sense the E1 was eating batteries like a hungry dog. Would a ans valve make my karni shoot better? Don't really want to switch to a mq2 for one they are expensive and I dont want to cut my cocking rod off the ics hammer.

Wgp are opposite of other regs you screw it in to raise the pressure (I think, but you screw it in opposite of other regs to raise pressure)

To sweet spot it, zero the reg out so no air goes through then raise it slowly till you get up to the right velocity

And also make sure you have a good paint to barrel match or else your velocity can also be a bit jumpy

Turning the reg in lowers pressure i believe and the lpr in is higher from what iv been seeing.

But im gonna try that. Somewhere else said to turn the lpr all the way off as well and start from there. Gonna try that as well oil it threw the asa. Just need to get time to do it this weekend.

set the ivg about 2-3 threads in. adjust the hpr to the desired fps. thats the general sweetspot for a karni. feel free to fine tune from there.

for the lpr. set it high enough to cock the gun, then a tad more for reliability. thats all it needs. it doesnt affect the velocity like the lpr on a timmy or ego, it just moves the bolt back and forth. keep in mind turning the ivg further in adds more spring tension which means a higher lpr pressure is needed to compensate. thus why you dont really want that ivg cranked too far in.

Hpr on the Karni works the same as a hyper reg from dye, in is off / no air and out gives you more air.. the lpr is the opposite, righty / in gives you more psi.
