djsyndicate123 · 10-05-2009, 10:14 PM

I'm new to angels so im not to sure whats wrong. I have an a1 magno'd with the newest software and i cant get my velocity over 145fps when i adjust the velocity adjustment on the reg there is no change in velocity, it doesnt go higher or lower. Any ideas?

test your pressures with the lpr and exhaust gauges. Also what kind of tank were you using and was the tank full?

cupseal probably separated.

Im using a dxs 48/45 lp air was fine and tank worked fine on my ego so i know its not that. the marker is set to the joy pressure settings everything was fine when i tested it. dwell is at 5.5. I changed the 9 volt. Thanks for the help. Anyone else have anny ideas?

I'd do what rangerjoe said and check the cup seal.

Thanks guys ill check that and repost if thats not it

sorry prob a stupid question but how do i get to the cup seal?

RangerJoe · 10-06-2009, 12:48 PM

unscrew front magno plug. stick allen key down and the magnetic cupseal will attatch. if the white cupseal is separated...replace it.

4mm allen key. remove the valve maintenance plug at the front (with magno written on it). point gun down. out comes cup seal/valve stem.

thanks for the answers. i pulled out the cup seal and everythin looks fine

if you put 2 fingers on the out edges of the white part... and try to twirl the metal part with your other hand, does the white part spin independently of the metal part? if so, then your cup seal is goner.

djsyndicate123 · 10-06-2009, 01:27 PM

the cupseal doesn't spin

Did you put the Magnos in or did someone else? You'll have this issue if someone forgot to put the valve body retaining pin back in it's place. Also sounds like it could be a bad ram. And try raising the dwell to 6.0-6.5. Most A1s work fairly well on a 5.5 dwell but it's not a definite thing.

It's a long-shot, but is your dwell SUPER low?

Rurouni_Ronin · 10-07-2009, 07:46 AM

What was your lpr pressure at???? Mine "drifted to 40" after getting it back from PA and wouldn't shoot over 230fps.

You prob need to add some shims.

145 is super hella low though.

djsyndicate123 · 10-07-2009, 10:02 AM

my pressures are at 55 and 200 and dwell is 5.5, I just swapped my ram out and justaiting for my buddy to stop by with a chrono to see if that was it.
