My Grandfather recently passed away, and I inherited his old Remington chain saws. 3 of them that have not been run in some time. Remington Powerlite PL-4 Remington Mighty Mite Featherweight 2.1 CI Remington Super 990 All 3 saws were used, but still look to be in fairly decent shape for their age. The last I can remember, all of them were in running condition, but have not been run in probably 10 years. I have read that they are great saws, and I was looking to purchase one anyway, So I would like to fix them up. I have spent two days trying to dig up research on these saws with little luck. I saw many posts from this forum, so I figured I would give it a try. I'm looking for some service manuals, Parts breakdowns, and some tips on how to properly restore these saws. If needed, I can upload pictures of each, and the serial numbers on the PL-4 and super 990. The might mite has no tag on it that I can find. Thanks in advance for all of your help.
