I inherited a saw that i determined to be an 041. Its missing the air filter cover and a few other plastics. I currently have the saw in pieces to rebuild it and get it running again but i am currently at a stand still because i need to know what parts to look for specific to my saw. I have found that there are many different looking 041s out there. The serial number is 113367190. I can take pictures of it but it is in pieces. Thank you for your help, this is a great site.
