Beer gun troubles

[Bullterra]

Just after some information I am using beer guns but have trouble with pouring half a glass of froth my hose is about 1 metre long and gas is turned right down any one have any idea what I'm doing wrong

Not pulling the trigger half way are you?

Either fully open or fully closed, anything else in between can give you froth.



Edit: and welcome to the forum

Could be anything.
System imbalance, overcarbed, etc.

Need more info - how did you carb for starters.

Dispense and storage temp too.

Line length sounds short, I run somewhere around 3-4m on mine to get it to pour well.
Wind it round the keg and leave a metre or so free.
Only use it when I'm taking a keg camping though so I'm trying to overcome all sorts of temp issues with lines out of the ice, keg temp ducking and diving as ice runs out etc
1m may be fine in a fridge.

Yeah try and balance your system. I find a 2 degrees I can run 1M 5mmID with reg set at 65kPa and get 2.5vols Carbination in the keg and get a decent pour. Approx...

Figure out what temp you like your beer,
then figure out how carbonated you want it
the figure the regulator setting to get proper carbonation
then work out line length balanced pout

plenty of calculators out there
