Hi all i just got a ec 300 2001 and it was fully rebuilt before i bought it.

it runs like crap i tried everything with carb that's perfect.

tried to do leak down test but its leaking from the power valve bearing.

any help would be greatly appreciated
 
That's normal. If you had sealed bearings, the "air" leak would be a lot less.
Check the reed valve.
