I use pieces of an old innertube from a car. Works fine.

What chrome, just a mirror polish til you run two tank with it. Then it's WTF when you pull it down cause of a loss of power. I hadn't looked at his 3700/4000 pistons, getting screwed on the 3400 was good enough of a lesson.

A set of rings might do the trick on your best piston.
Did you have a chance to do much cutting with this? Someone mentioned they still liked the PP5020 better than the PR. I’ve been tempted to grab a PR when they are marked down to $150
No it was brand new and wouldnt stay running from get go. Owner was with me so fixed issues and he left.
(My PP5020 was same way out of the box)
I do hope it comes back in a year or so. Like to see those newer fuel lines they used and how they held up. Then maybe I can cut some too.
Always a good choice right @chipper1
Let me know if you get some trigger time. Like I said I looked at it this spring when they were 150 delivered but then I was buried in project saws which I have yet to see the end of.
Side tensioners rule, except in the case of certain saws for noodling.
I wanted poulan 71cc with side tensioner. So made a 372 one work.
Mentioning covers. Hard to find ones for these poulans I have too.
Lucked into a metal one on a jred 2077 I picked up with a echo 8000.
Looks like a collector wants this stuff for his 2077 with broken plastic cover.

Picked this up from a sale today. Recoil is broken. Rest of the saw looks like it barely has seen wood.
I have a parts saw at the cabin that I’ll trade recoils with.

Guy needed a coil for his poulan. Told him I would pull one from a running 3300 I had. Showed him video of it running on CRG and then pulling from saw.
That way we both know 100% working coil sent.

This is why I pull known good coils from running saws. Pulled one from 33 parts saw and was no good. So onto to another one and good to go.
Would just fire off sometimes. Tested old school and new tester both show no good.
One from the 28 was good. So the CV19-2 is back up and running.

Its funny this talk of bad coils, as I just experienced this for the first time. Couple weeks ago, before this crappy hot weather hit, I was bucking up a fairly large Maple tree with my most used saw, a 4000. Been running quite a while when it did its thing a saw does when running out of fuel. Falters and goes lean and quits. I refueled and drank some water and a short break. Went to refire, and nothing, not a pop, fart or anything.
I tried choke, even tried pouring a little down carb. Nothing. Took it back to barn, pulled plug, looked fine. Gave it a pull test with plug out of saw, no spark. (yes I checked to see if switch was on)
Tried new plug, still no spark. Figured it had to be coil. Robbed one off a 3400 and yahoo, spark again. Couple pulls and saw fired back to life. That is the first time ever that I can remember of having a coil "go bad". My question to those a lot smarter than me, Is what actually goes bad in the coil? Not like there is a lot of moving parts happening in there,
Gregg,

Possible a break/ burn in the field winding, transistor burn out. Same as a older style coil in an automobile. They quite for no apparent reason.

Not including the blue module Homelites, coil failure is fairly rare. I have only had a few bad coils between nearly 30 years of cutting and owning a low 6 figure number of saws since acquiring CAD.Its funny this talk of bad coils, as I just experienced this for the first time.

Gregg,
The wiring within them can burn through, and often the housing cracks and moisture gets inside and wrecks stuff or shorts them out. Sometimes if you have a coil with a cracked housing you can bake it at a low temp to cook the moisture out. We did that with one of my trucks. It died in my cabin driveway and after a wet snowstorm there was no way we could tow it out so we heated the coil, got it running, then drove to the parts store for a new one and drove home without shutting it off so residual heat would keep the coil dry.
Several times though, I have had a saw quit with no spark to find that the flywheel to coil gap was too open so I re-gapped with a business card and went back to working. This is most common when someone else had been working on the saw before I acquired it......
There are some solid state devices that are incorporated into the making of the coils and solid state devices can fail from excessive heat.
Keeping them clean will help keep the coil cooler.

More likely the capacitor, item 146, just like your home AC unit...but that main Darlington transistor 158 is highly suspect.
Holy crap! See what I mean about folks that are smarter than me on this subject..
That might as well be battle plans written in Russian. I'd be lost and probably dead. lolGregg
