So about four months ago my neighbor brought over his saw. It was the Poulan Pro 4218. He said it would not run. I could have it or dispose of it. He wanted it out of his garage. So after it sitting a couple of months I pulled the carburetor off. To cut to the chase I replaced all three gas lines along with the primer bulb. Added mix and three pulls later it was running. Adjusted the carb as it was way to lean. The muffler next got my attention. How this thing could run at all beyond idle was a surprise. I will add that the piston was spotless. So now with a chisel and a small persuader the baffle blocking the exit port, well it now has a more useful function. So now with the saw running well and also oiling it was time to see if this implement would cut. I did sharpen the Oregon 91 series chain on my Jolly Star. Anyway this saw cuts wood like you not believe. I never owned this brand however it simply cuts great. Way more performance than I ever expected. And it was free. I have about $6 between the gas line and primer bulb. Anyway this was a bit of a surprise. For a cheap saw it is well worth the price. Ken

I have repaired a LOT of these saws and as you have discovered they can be excellent runners with the mods you have made. The usual problem with them is they are purchased at box stores by people who know NOTHING about chainsaws and the factory carb settings are usually too lean so the owner either fries the top end or gives up on them because they don't run right. Being a strato engine the H screw often has to be at least 2 and1/2 turn out, sounds like you got it there.

These have plastic internal transfer port baffles that contact the piston...its wild

How can those baffles last longer than a couple of years of average usage? Maybe that's why these are now judged as throwaway chain saws. We have become a throwaway society. Yes, that is wild and also rather sad. :nofunny:

I replaced the cylinder on a husqy 240 and the plastic transfer inserts in the fubared cylinder were actually still good.

Likely it was straight gassed and that will destroy the piston and cylinder in 12 minutes or less. The plastic transfer inserts might last a lot longer than 12 minutes. So, they were still intact.

This one was dull chain and a little to lean. I mixed the fuel for the saws that day someone else cut rocky stumps with it.

I rebuilt one that was too lean out the box...burnt up in 3 tanks, the baffles were fine but wear there was already evident. Good news is these things will lunch themselves before the plastic wears out. I rebuilt it with an 30 dollar ebay top end and gave it away.
