Steve, I'll try and take a picture later tonight to post. The cushy handles are nice, and my 8500 had one as well before I put a full wrap on it. Let me see what I can do this evening. Max.

Steve, I found this saw in a CL add about three years ago. I went through the saw, but the oiler worked poorly IMHO from day one. I recently went to help a friend with a very large tree at his home and it stopped oiling altogether. So, I found a really nice used oiler in case I needed to replace the one that's on the saw. I just replaced an oiler on a Homelite 8800 this past week, and said to myself now is the time to get some saw maintenance accomplished. It could be a poor or damaged line, or a stripped oiler gear so I wanted to be prepared when I went into it. It's heavy, loud, but a good looking and running machine. Glad I was able to find it. Best, and I'll post my findings here. Max.
It's exciting to say the least when the clutch leaves the saw at high speed.
I've looked hard for that kind of handle wrap and have never been able to find it even though it's still made for wheel chair / walker handles. Lot's of soft bicycle stuff that doesn't last. The stuff on my 8500 is perishing.
I looked at the Limbsaver online, didn't look to bad.

Lee, Did you get anywhere with the 3400 / 4000 swap?
Cut a large pine tree down in a neighborhood close to the house and main road, dropped it perfect in between two parked cars. Used my 365, 3500 & free S25DA I got in Oregon. Realized what I did after I was all finished. My saws are all sticky now. Oh well the job is done

Should be a very easy swap. Question: Is there really a performance differance between a 3700 and 4000? What, there is a 3cc diff. in size.
Here are the actual displacement numbers in that series for the heck of it. The stock stroke was measured by a machinist that made a stroker crank for a 3400.
Poulan 3400, -4000 saw stroke is 1.319"(33.5mm) and displacement
Volume of a cylinder V=πr2h (volume = pi X (radius squared) X height (stroke)
3400 3.14159 X (1.81/2 )squared X 1.319 = 55.614 cc
3700 59.681 cc
3800 59.9999 cc
4000 63.562cc

That's a good question Bob. I'm not sure because I haven't run my 4000 in wood yet. I have 3 X 3700's and a bunch of 3800's. I'm not even sure about the 3800's and 3700's. Without comparing two in good shape. I suspect at the end of the day there wouldn't be much
On paper there should be some as the 4000 is about 6% larger. There's an obvious difference between a 50 cc saw an 60 cc saw.
I guess someone needs to run the two together, same B&C in the same piece of wood to get a general comparison.
Without testing, I can say that my 5200 is faster than my 3700's
Tim,
Do you think that I should use the 4000 FW and recoil or stick with the 3400 FW and starter? I have a nice 20" B&C for the 4000 when finished.

Its just my opinion, just swap p/c and leave the rest as is.

I would use the 4000 FW and starter. Why? Because it has the 4000 decal on it. If the label is fubared, take your pick. The Craftsman 3.7-18's are 3700s with 3400 / 3800 flywheels and starters. My 3700 comps are around 170 psi and two of them have 3400 set ups with no issues. Mind you, us collectors aren't generally of the 30 pull start rip it apart guys.
I switched one 3700 to a 3400 set up as there was a crack in the FW hub on one and I didn't want to be one of the guys that blew up a flywheel.

I thought I was the only one who blew up flywheels! Lol!
I was wondering if the timing would be the same with either FW? 4000 decal is good so I think that is the clincher.
Same case, crankshaft, timing should be the same. You can match up both flywheels .

The only diff in the flywheels are the starter pawls. They are fastened with splined rivets? that are pressed in.
3700 and 4000 use one type (pulleys are different though)
3400 and 3800 use a common flywheel and pulley
I believe the starter covers are all the same.

Haven't messed with but one of those carbs so i don't know the correct setting but that looks to be too low to me. Fossil or Acorn should know more about those, they are more knowledgeable than I on those.
