Gregg i recognized something when you turned it to the 5200 sticker side is that the new one ?
LOL, No Calvin. I havn't put the new one on yet. Saving it for when I repaint, and or find the right side decal also.
Gregg,

Do you have or have a lead on any 4200, 4400, 4900,5200, 5400 saw parts.
I have a working ASFAIK 4200 & 5400.
I threw away a useable piston from the 5400 and a repairable air filter
with a little tear on top years ago.
I had no idea at the time parts were going to so be hard to find later.
Christchurch was near the epicenter of the recent NZ earthquake, probably
a good reason to get as many saws as possible running for cleanup.
3/8 chain is what I run. I too like the reed valve saws. The 5200 and 245A I have are reed valve types, and both are strong saws, don't turn the rpms, but alot of torque. Don't know if you knew it or not, but the 85cc Poulans have a governer in the carbs on them. Pretty much have to adjust them in the wood.
Gregg,
Well, you probably know more about it than me, but to my mind it seems a very dumb idea to have a very soft bore and a hard piston and ring.
Briggs and Stratton had the same idea with their alloy bores in the home owner lawn mowers. 4-stroke, lot's of oil slopping up the bore and they still don't last as long as the cast iron bored ones. It just seems a bit short-sighted to do the same trick on a 2-stroke.
I don't know whether the 3400 had some sort of coating on the alloy, or whether it was straight alloy, but I think if it's straight alloy there are better ways of designing a bore, otherwise everyone else would have down the same trick.
As you say, there are plenty of them still running, so perhaps there's something in it.
Cheers!
No, I didn't know about the governor - handy to know! My 2101XP had a governor on the carb but the boys on the forum said to block the thing off as they get old and don't work properly. Now it runs like a dream, and compression went right up once it got the right mixture. The governor was letting so much fuel through that the rings couldn't bite.
Is the Poulan governor the same system of ball and spring, or something different? Is it worth blocking it off?
Cheers

They are DEFINATELY worth blocking off!
Just ask Modified Mark!

Maybe I need to relook at how you block it off. Calling ModifiedMark!Bob
He is relaxing on the lake this weekend!
Well beside the lake anyway.LOL
He should be back tonight.
I hope he gets in pretty quick, I have a couple of jobs for him!!!

I have never seen a chrome plated piston.
All the Poulans i have had apart were a chrome
bore and cast piston.
