We are running a 7.5hp with a 10gallon tank through a matched compressor. We have a back up tank connected to that, and we run our 6/8 gauntlet, our 10/12 xpress, our svecia, and roller master all through it. the xpress and svecia don't have any issues with the stuttering...but we do need a new oiler on our press, maybe it's just running dry

Adjust the oiler to approx 1 drop of oil per every 7-8 revolutions.(critical)
Homers right on the airlines! Crank up your air pressure as high as it will go to the regulator. Adjust
between 105-115 at the regulator. don't forget to adjust flow control valves on the bottom.
Also Drain all the sludge from the bottom air tank. (press frame) . Cut the air, unloosen the plug,
and blow it out.  Get all kinks or replace air lines as needed. Grainger has it 5/32",1/4". The cool
thing on these old gauntlets, is that you can retrofit and "trick" the heck out of them. You can increase
stroke cylinders also. When the presses were designed 16 newtons was tight. The Looser the screen
the higher off contact. If you use higher tension frames, drop your off contact. Make sure squeegee rubber
is FLAT... Round corners so edges don't turn down. Sufficent air pressure is critical on all air presses. They can
fly if you treat um right!

For us, also 7.5 horse screw/chiller/tank, 3/4" line.  Prob not an air supply issue for us at least, surprised how little the compressor kicks on actually.  The rods on our stroke cylinders feel very well lubed to me and I think the oiler is running fine from watching it when I set it, if anything it may have been over oiling. Our flood seems fine but the stroke "chatter" is more like the stroke cylinder starts pulling and the blade hangs out and can't move (at some speeds) or comes slowly and then speeds up, like it's caught on the squeegee edge and can't break the surface tension.  Probably just the nature of air heads but I could see where a stronger stroke cylinder might be the missing link.  I mean, if you beef up the choppers but the stroke cyl can't pull them consistently at that pressure, well what's the point?

On the valves I was kind of thinking I should've just bought a brand new mac valve bank for this thing instead of the two single 45a's I have coming.  It would eliminate a lot for trouble shooting.

Brilliant idea, def going to do that.  I have all this wonderfully clean, dry, perfectly lubed air running into a tank full of god knows what. 

So you can increase those stroke cylinders then?  Looks like there's some serious room for upgrading there, what do you recommend?

1/4" or so . Don't go crazy unless you have larger compressor. (critical)
Do little things! They really add up.
good luck.
