Looks like he's holding the trigger down. I was looking to see if his finger moved but didn't see anything. Lawn sprinkler is the first thing I thought too (after the 400 psi comment, of course).

I'm guessing there's a weird aftermarket on/off in there since it's old enough that it's using the powertube spring.

Get a proper reg. That looks like some sort of SP reg which you need to make sure is HP and not a LP reg. You need at least 800psi going to the marker. Anything under that will cause hiccups at higher BPS in some setups.

Mags below 500 psi are real squirrels sometimes.

There's your answer. tjd, you state in the vid that you have a new teflon o-ring. Did you also replace the urethane o-ring that goes around it?

[Ando]

The teflon one is the sprinkler oring and there's probably nothing wrong with it. It's probably not sealing right due to the air pressure or he might have one of those funky old on/off's.

I am holding down the trigger in the terrible video sorry about that. The SP reg is a HP maxflow so it should do 800 no problem (assuming I have it in the tank) But for testing I will switch over to a regular tank. I did replace all the orings urethane and teflon both. I did order one of the spacer kits and some new reg seats from AGD (cant hurt right) I am pretty sure I have the pin in correctly it has a ring around one end and I put that on the bottom. I will take some pictures of how I have everything assembled once the replacement reg seat comes in and I take it all apart.

Not all maxflows are HP.

I know I am a long term Maxflow user. I know that this one is a HP due to the small piston.

AGD spec on classic style valve is min of 675 to reset operates best 820 to 870.

Also, oil the crap out of it when reassembling.

[tjd10684]

will do I still have not gotten my replacement parts so I have not taken it apart yet. I am using air tool oil rated for incidental food contact any body know something better to use as oil? I have used ATF for blowbacks years ago but I figure it would be "green" of me to change to food contact rated oil.
