In fact both the PP5020 and PP4218 are a bit zaftig, the 4218 almost 3 lbs heavier than RedMax GZ4000, and both summat bulky. (Lose the Torch plug from the 4218. Really! Now!)
They both rip- end of discussion for me. And ... being stratos, no need to lug much fuel out on the trail. Sure, I'd like them lighter, but for me, other (legal, mind you) addictions vie for bucks.
With a decent plug, both start reliably, and make lots of chips on a tank.
Recently, cutting up Sandy damage, the 4218's been getting the bulk of the work as it's been breaking in. But, seeing insulator of CJ-8 running bony white all the way to the metal shell, it now has an NGK BM-7A (CJ-6 equivalent.) Fouled plug no problem, moth-eaten piston BIG problem- won't go there.
Almost forgot- Carlton 30LP chain holds edge MUCH better than OEM chain on PP4218. MUCH better.
