Was it a way off big squish aftermarket one bought on the cheap?

Where'd the OP ‘Welderman85’ of that rebuilt Poulan 4218 wonder off to?
Yes Kevin, it was a new AFM kit that he installed.
No build dimensions of the final squish nor ring end gaps were provided, so not much help here.

Least other brands keeping me busy. 
All the poulans I sell dont have to come back to often.
Old sign I am hoping makes it to me someday. It's mine, just not in my state. 4'x5'

They have it stored inside to persevere what's left?

That Weedeater one looks like an old Weedeater I use to have. I've owned a few of their models. Last one I had was a Trim-n-Edge. Ran it ten years or more til the throttle cable broke, was NLA. Really liked the auto line advance, worked pretty well.

How can you tell when a bar is junk
When bent or the slot in the bar is too wide. If it's worn evenly you can consider going up in chain ga. ie., .060 to .058 or .063
Sometimes you can save one with the wide slot by grinding the rails down. You can grind them down so the slot is no shallower than,
Chain pitch Minimum groove Depth
1/4" P 4 mm
3/8" LP 5 mm
.325" 6 mm
3/8" 6 mm
.404" 7 mm
If the bar has a sprocket nose, the tie straps shouldn't be touching the tip as the chain goes around.

How's that 4218 coming along with the compression?

sorry I'm here my phone got smashed. Mine was a china p and c from Ebay. I gave up on it and put engine from a non av saw in the av chassis.
I gave up on the Ebay kit and put a good 150psi engine from a parts saw into the av chassis. Once I tore it down and compared the china parts to the ome parts al the ports were different. Different sizes and shapes.
Some times it cheaper to get a donor saw with a good p/c. Some folks will almost give them to ya when I comes to the plastic Poulans.

I bought a used piston and cylinder for a wild thing once. Saw ran so good I traded it for a 3400. I got the wild thing for free.
I pulled this from a back of a shelf yesterday. It is a oem good used transplant for that slightly scored 4218 I tested psi on otherday.
I just never could make myself do that saw and been setting there years now.
Dont help that I also had a like new 4218 and a green version on the shelves ready to go for locals on the cheap.
Pulled them down to get a guy here a idea on the L H settings.

Some some reason I ended up with 10 plastic poulans this winter most were free the rest were less than 25 . I'm new to saws and figured they were good learning saws and they turned into fun little projects
I been using a plastic homelite for my root cutter this spring. Dont owe me anything after I got it running.
It came in like this a year or so ago. I tried to tell him I didnt want it. But he left it.

With nothing better to do, I’m working on my 4 s25da and cva’s. Going to replace the top handle rubber on two. Thinking of using a section of garden hose, though one of my others looks to have auto heater hose as a replacement. Has anyone used either one? I’ve replaced many a golf club grip using
Two sided tape and naphtha to ease slipping the grip on. Figured this might work on the saws.

I seen some stuff once on Amazon that's made to go onto handles. Came in different sizes and colors. They pictured shoves, rakes, chainsaws and pushmowers. Had different thickness of cushion.

These things will give you a education. They can keep the blood pressure up.
A 4000 with a 24” bar is like a hot knife in butter with this southern pine !
