Well if it isnt raining tomorrow I'm going to have a mini gtg test session.
All stock no muffler mods or anything.
3 saws not broken in 550 2nd tank, 545 on 1st, 5020 on 1st. All saws are set up with 3/8 7T. Will be running same chain stihl rsc off the reel new.
I dont look for the yellow JD 450 = echo 4500 45cc to do well pulling 3/8. Being that saw reminds me of a husky OE 45cc 346. The grey craftsman bare bore / chrome piston is similar to the poulan 3000 chrome bore / bare piston. I just dont know till on it. Will know soon

The poulan 5020 is a 5016 to me

The orange ones speak for themselves.
Cant post a pic of the test mules do to PB being down right now.
