drock59, page 24 pics. page 21 mod. thats all i've done except
for the metric to standard true union, which probably wasn't
required. same as the flowmeter. choke the air knob, same air pressure as wide open. only starts to go down when air is nearly
all but shut off. save your money. less air~ less bubbles more
flow required. more air ~more bubbles less flow required. it really
doesn't need much tuning. bubbles seem the same size either way, remember it gets chopped up by the same wheel. works
good enough.
