I agree with Mike and others. 120psi is acceptable. Generally, the grey/black craftsmans were 3800 unplated bore plated piston, the red/black saws were 3.7s and plated bore unplated piston. but there are exceptions to this rule too.

As I posted in your other Thread on this subject, 120 is fine . Have many a saw that started and ran great at 120.

4200 piston does look bad cylinder may live again

Yes the 4200 uses the same seal.

That piston looks very bad and I have my doubts on saving that cyl but you never know.

Good luck in finding parts.

Hi Mark
Yes the piston looks bad, even worse with the cylinder off!! ugly.

Looks like a broken fuel line going into this elbow brought may have caused the lean seize.

but will change out the crank seals for good measure when I get all the parts


The cylinder cleaned up pretty good, now just to wait out and find an affordable piston donor and rings. Guess that too is part of the fun

Assuming this is the right stuff for the 4200?

Dave that is a problem with those, there a odd size for todays replacement lines.

They use a 3/16" ID but the only line that I can find today with that ID is also a 5/16" od which is pretty big and stiff. If makes it tuff for the line to float around int he tank to follow the fuel in different postitons.

It can be used in that saw but is also tuff to get pulled through the tank hole.

All of my saws in that series now have a two piece fuel line setup in them. Id did my first one with the screw in tank fitting from a Poulan 361 which used a 1/8"ID line on one side and a 3/16" ID line on the other.

I had to tap the hole in the tank to accept the fitting
.

The 361 fitting is NLA and Bob Wright being the super nice guy he is turned some more out on his lathe for me.

I did aquire two brand new original Poulan fuel lines for them and they now set on my shelf as the 2 piece setup just works much better. If you do a search here on the site, I did post some pictures of that setup.

.

Guess the previous owner thought the same but it didn't pan out so good for me.... Guess all the talk about replacing fuel lines is just not idle chit chat, it can save an engine

may I ask what you did to clean it up? it looks about as bad as the one I have trashed right now and I am hoping for some alternatives.

thx, vic

Hi Vic
I used 400 and 600 grit wet dry emery paper. Went sparely, over the combustion area, just enough to remove the aluminum transfer. There are a few pits in the chrome below the exhaust port so hopefully it will seal properly with better rings, and work ok. Someone with more experience will probably chime it and let us know. It was worth the few hours of rubbing.

Didn't use any acid (had none). It may have dissolved the pits even bigger, possibly ruining it. I just don't know....we'll wait and see.

Ron, I like that muffler mod, they work, and there quick and easy. No welding and almost anyone can do one like that.

Why in the world you got that funky creamsickle chain on it though?
 
Just snagged a 5200 on the bay. Only one pic and the seller said it might or might not run, but for a $50.00 buy-it-now I figured it had to be worth it even just for parts for my other one. I will post a vid if I get it going.

Say it aint so !!! cant be a creamsickle chain with that lime green link in it ??
i deny ANY responsability,it's what came on it when i got it :msp_blushing:
 
that bar is just over the top. My 8500 is begging for a bar like that......if there is any chance that you would want to part with one please PM me. I would love to make my saw look like this.

It now wears a 24" bar.

Sorry Steven but those bars will not help ya. They have a 14mm slot like the large stihls and dolmars. They are specific for this saw. You could always make some sorta spacer though but it just wouldnt be the same

Your saw already has an original Poulan/Windsor bar on it. What's wrong with that?
 
I had a chance to use the S25CVA again this evening. It's still breaking up once it gets hot. This one has me stumped. I've replace the coil, installed a nova module, and replaced the sparkplug. Can a flywheel be bad? I don't know how it could, but I'm at a loss at this point.

In the mean time, I finally got the other one done and in the wood. This one is wearing a rim sprocket, so is 7-pin instead of the 6-pin spur. I'm very happy with the way this one runs.
