If there is no oil in the area of those seals then they are fine. And they are easy to pry out just use a screwdriver. Are you still working on the BR400?

I'm going to order the seals today. Yes still working on this 400

Starter side, the Seal just fell out when I took the cup off. I assume this means the seal is DONE! Is that bearing supposed to look like that? Seems to be missing some bb's.

The Seal #1

The Seal#2

Flywheel Side

Does this seal look bad?

Need to be replaced?

Kieth...Probably a good place to stop...The ball bearings that are missing have been ingested by the engine...never works out too good...
Stick a fork in it...its done...

Why do you say its missing bearings? Looks like this one only has 8 as well.

I stand corrected...The cage that used to hold the ball bearings is what the engine injested.
Doesnt change the prognosis...

I hear you, but how would that cause an engine with perfect compression to not start? I'm not going that far with it though. Not that I don't feel that I'm able, just don't want to spend that much money on a free blower. Either way I have the new seal coming. I'll replace it and see if it grenades afterward.

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.
