We you are dong fine put those seals back in and good to go. I am assume this is the BR400 which is two stroke? Actually the BR400 and 420 are maybe the best blower ever made. I got 4 of them and 13 Echo units. I just had seal come out on Echo PB620 and it kept starting so the crew kept using it until a ring broke. Fortunately it didn't do much damage and I am putting a used piston in it some rings and seals and I am certain I will be good to go.
I get a lot of good parts from the local dealer where people run raw gas in the units and then don't have them repaired. I did repo on 4 a couple years ago and all are fine.
