Summit Kegerator Initial Foam Issue

Good morning BAs,

About a month ago I bought a Summit SBC 500. I have run a sixtel of Alagash White through it so far and the carbonation on the beer was just fine, great. Every time however when i start to pour it spits out maybe half to a third a pint of foam before the beer itself begins to flow and i end up pouring out a lot. The temperature inside the kegerator is 32-34 degrees and the PSI is at 9-10. I had the psi at 12-15 for a while and it didnt seem to make a diffrence so I have been slowly lowering it. I will note that the few times where I have poured a couple pints in a row the foam spitting issue seems to be mostly negated, but it is still there a little when I first pull the handle down. There is maybe 2 feet of line between the keg and the faucet. My wife bought me a keg of enjoy by for my birthday and I wanted to see if I could fix this foam problem before tapping the enjoy by becasue its a much more expensive beer and I dont want to waste a lot of it by spitting out foam each glass. Thank you for any input!
