If it's American lager like your post a while back the 2.2 - 2.7 Vols CO2 so select something in the middle and if it's over/under carbed for your taste then change it next time.
OK shaking your starter every time you go past it will increase your yeast count, and good luck if the weather is warm it may help keep the temp up as these beers are best fermented warmer than ales (but start low if you can)
Fair enough I make mostly foreign type beers, German style Lager, Wheat Beer, AIPA etc and had to resort to smaller dia lines to cope with the high carbonation levels.

3/16" by any chance?
