Factory echo part
This carb was for a 1995 cs-3000 trim saw. Was told this little saw wasn’t repairable. It was is good shape and I used it all the time since I trim trees for a living. Got this carb and some other small parts for it. Now it runs like new. Best place to get parts. I’ll always come back ! Thanks Doug-Affordable Tree Trimming

Replaced carburetor, wish is came with a gasket to the base. Had to take it back off and put a little sealer on it to get it to idle right. Also put new air cleaner on.
