Air Bubbles in Shocks?
I am rebilding my losi 8ihgt shocks with new o rings. I have the losi shock balancer tool. What is happening is I fill the shock up, push it up and down to get the air bubbles out, wait a night then push the air bubbles out again, then I screw the cap on. I push it around a few times and when I open it to put more or less fluid in there there is a BUNCH of air bubbles!! the o rings are new so I want to know why this is happening? It's been 2 days and I havent even got 1 shock perfect yet!! thanks!
