Ok...well...now Im totally confused...although what you two say seems to make more sense than what I had heard in another forum. I was told that the Pixi is over shimmed????...I mean...
it is good with no shims for 30% and that to run a lower % , one would have to have the head button machined down. I can say, as for right now, it is running great. Although I have only run 8 tanks worth so far...despite beautiful weather, I have been sick all week and havn't had desire to do anything
