Straight and to the point. Thanks for sharing.

Super cool bro. Thank you very much. I feel so stupid. I ran my Jonsered 621 with 40 to 1 instead of 25 to 1. It died and has low compression.

When I adjust the idle screw I cant make the chain spin. It seems to idle okay though. When I give it gas it bogs down hard, if I slowly apply the throttle I can slowly amp it up to full throttle. It outputs too much bar oil. Any idea what this may be? Seems like its not getting proper gas...

Thank you for a great video!

Great job at R&R!

Great vid. Very good filming. ….. can you do mine ?

good job

Thank you! Great video! Right now I am fixing an old 2035. Are you shure the old sylinder is broken? After a piston damage like this, the sylinder looks bad. But after removing material from the soft piston, (that looks like scratches) it is sometimes still fine. At 10:16 "Now we put on some silicone". It is a silicone gasket, a hardening sealant. Not that kind of silicone sealant we use in the bathrom. And make shure the groves in the krancase bottom is filled. Clean the surfaces with som petrol or breake cleaner first.

How to sharpen chain saw chain with hand file.

If you want to see good chainsaw builds go to ironhorse chainsaws. And hand filing bucken Billy Ray smith. You will learn things there.

Man, my saw has zero compression.... no way I'm getting that fixed today

Just a tip, if you’re going to attempt to inform others regarding this type of operation using a second language, then perhaps it’s a good idea to first learn the correct terminology. Just sayin!!!
