I try doing my first carburetor rebuilt...chainsaw Stihl 020 AVP. If someone have some suggestion or corrections...please feel free to comment ! Much detailed clip...I think. I did a mistake in leveling link arm for needle lift. You see it in the clip...and I wright comment on it. I think this saw model is special good...well balanced and much power compared to wight. Not that easy to get a brand new carburetor ...affordable price. I like to try do mechanical work...of course ...and the magic when it work as it should do... if not done any mistakes...that is.
