Invert Mini Chopping?

[Ancient Blonde]

Hey guys, I have an invert mini, and it's breaking paint quite frequently. I have it set to about 250FPS, and it still is, what could be the problem?

Eyes might be broken. Or you could try putting your settings on the board back to factory and see if the problem continues

[neogred]

Or make sure there are fresh batteries in it

[Hunter]

both wise answers.

I put brand new batteries in it, and also have the eyes working; if I turn it on without my hopper on, and without paint in the breech, it won't dry fire.

[Hunter]

if you have tried those it may be breaking i. the barrel. what paint are you shooting? did you do a bore maych to.make sure your bore is large enough. how old is the paint?

[Ancient Blonde]

Paint is brand new, marballlizer, 691 bore, stock mini.

Whats your pressure and did you try any of the fixes in my previous post?

[Ancient Blonde]

Yes I tried the fixes I thought could be causing the problem, haven't been able to test it, and I'm at 300 PSI in my regulator,

WHOA slow the **** down man. First of ALL lower that puppy to 160psi.

Here is my tuning method that has gotten quite a few minis and axes shooting great:
1) pressure to 160psi
2)back cap ALL the way in
3) bring the cap out until you stop rising in fps (shoot like 5+ shots to confirm rise/drop in speed)
4) put the cap in just a little bit (not even 1/8th of a turn)
5)Adjust velocity through regulator (shoot 5+ shots to confirm rise/drop)

You may also need to buy a new gauge if you are going to 300 or over (on the v2 or v3 minis, not v1)

I'll tell you what's wrong. Your shooting an invert mini.

[Ancient Blonde]

I'll do this! I'm hopefully getting access to a chrono this weekend.
