Jerry, Like Mark said, the plated piston/bare bore, is NOT a problem whatsoever. I know its not the norm, but my first saw I bought new, was a 3400 in spring of 1986. Was the only saw I owned until 2008. I heat with wood, and cut a bunch in that time. The saw still runs like a new one.:) Maybe it was just luck! But, I doubt it. Was a pretty good design in my book.

:cheers:
Gregg,




It wasn't just luck!!!
I have several of these saws in the shop and all run like a top!!!

As it is on my bench at this moment!
This is the CVA, its torn down as far as it needs to go. The crank seals have been removed as well. All parts have been cleaned, next is the rebuild. New seals and gaskets (except base gasket thats getting motosealed) clean up ex port, rebuild carb, new fuel line and filters, clean and re-set points put it back together and hopefully it runs!

What do you set a 3700 up at (rpm's no load)? I have one that I've "tuned" on a little and it's 4 stroking at 13k. I will put it in wood tomorrow night and see how well it does but it certainly appears to be a screamer.

Good question Randy and I cannot say for sure. None of the manuals that I have seen have ever listed a no load RPM for them and truthfully I don't think I ever tached one out.

I never seen the need to, just tuned them by ear and in the cut. I finally bought a tach myeself in the last year, just because I had a couple of rev limited saws here.

I could check a 3700 for you if I had a stock one. :hmm3grin2orange: Ones been muffler modded and the other has a mild port job.

I don't have a tach, but think maybe I should. The day before last years Poulan GTG, Steve (67Mustang) put his tach to my blue 4000. I don't recall what it was (CRS):dizzy: but it was way up there! Scared me. So I quickly richened it. Now I been running them too rich I fear, out of fear..LOL

The manual only says "Under no circumstances less than 7/8ths of a turn from lightly seated".
I am SURE that I have seen somewhere that 11,500- 12,000 is the no load on them.
Operating (in the wood) rpm is 8500 according to Acres site.

Thought I would show off some photos of a Poulan we used once on a boys trip down in Tasmania. Bought as a $30 garage sale special, first time we used it was when we came across this track. We had heard from locals that the track was blocked due to a landslide, thought we would go check it out. Turned out to be a big tree that had dropped down into a ravine where the track ran. Tree was probably 100 years old and been dead for another 100 years, once we got through the rotten crap it was granite hard underneath, dont know what kind of tree it was. Saw ran more or less continuously for a few hours cutting the tree into about 6 large sections which we dragged down hill and dumped in the river. The last piece took two cars towing and one pushing to get it moving. When we first started the saw ran like crap and broke down horribly in the top end, few adjustments later and it was a screamer up top and slowly got through it all.

Mike, maybe I'm running mine rich but to me 10,500-11,000 seems right. Even at 10,500 they seem to scream. Any higher than that and I feel very uneasy. As for 13,000 or so I just don't think a stock 3400, 3700, 4000 is designed or will last that long.

Gregg,

Gregg, like I mentioned to Mike, 10,500 -11,000 seems to be right for me. At least that's what my POulan 3400, 3700 saws seem comfortable at the plug is a nice light brown.

Joe, I take it crank seals are still available? Also in your work on the saws have you seen pistons w/o ring pins? I have two saws w/o them and two with. I presume you place the ring ends on pistons w/o pins, oriented toward the intake port. Haven't really run these saws yet, so I want to be sure before I screw something up.

Is it stock? 13,000 seems high to me but you never know. I'd cut with it and shot the saw off while at full throttle. Then check plug color. If its light brown or so you're fine. If its gray or whitish you're too lean.
