Kevin that's the "underrated" 3400 Sears sold as a 3.0 to meet a lower price point.  It's actually a 56cc 3400/3.4 with different badging.  P/C/Rings part #'s all match the 3.4/3400.  Was a major case of getting more than you paid for.  Seen a few of those.  Worked on a few when I worked at Sears Service in the early-mid 1990's.  IIRC, I worked on more of the "3.0" saws than 3.4 and 3.7 branded CounterVibes.

I just noticed the file name for that saw manual photo.  "crapchainsawpic".  WTF?????????

One dang number marred.  Craftsman 358.356081

Thinking this is the craftsman 3.0 by numbers here that is really a 3.4

Kevin use a popsicle stick or plastic straw to measure the bore of the gray saw. Do the same with the 375 and compare measurements. If the gray saw bore is close to the 375 measurement, then it is a 3800.  3700/375 and 3800 bore measurements are just slightly different. A 3400 would be smaller...

Betting the smaller 3.4 sold as 3.0 due to the 358 number above on it.  Hope it is a 3800 though, but would bet against it.   
I will find the bores and post it here too.

Some info I have saved in the poulan 4000 thread.

4000 bore 49.2mm

3700 47.7mm

3400  46mm

The 3400 run around 125 to 135 psi.
The 3700 will run around 150 to 160 psi
The 4000 is the same as the 3700 they both have two thin rings and the only real difference is in
the bore size as far as compression goes.

I have seen the exception posted where someone got up to 175 psi on the 3700 and 4000 models.

Any other info just add to it.  Thanks

Craftsman 358.356081 3.0 3.4

I bet right. 

Just checking through exhaust port. It is like 46.2mm give or take some and chrome piston 2 thick rings. So one of those craftsman  358.356081 3.0 that is really a 3.4 

375 was the 2 thin ring bigger bore

If there is a poulan collector interested, just holler.

New owner put his gauge on the 3.0 3.4 and 375 to check psi. I never did as they felt normal ranges to me.

3.0 3.4 135psi

375 150psi

Good numbers for both.  Doubt they pushed any more than that when new.

She wasnt scuffed in ext side looks sweet.

Now maybe intake side might be suspect after seeing air filter.

So on hold parting it to see if can be a runner. But thats on back burner while doing other folks saws and fishing. ;)

Above is the kind of stuff I been seeing alot of latley.

She oil runs and has good psi for a 3400.

After getting good and warmed up, Didnt pass the redneck crank seal test.  Noticed idle rise when on pto side down.

3400 etc. OEM 530019097. SKF 6119 for double lip. SKF 6120 for single lip. National 253747.

Placed a order with Advanced Auto for seals.  National and ordered 8 of the 253747. =
Well pizz. Got my order and no crank seals in it. They canceled that part of order. Oh well.

So = Rockauto shows both of them online to ship. So ordered 6 SKF 6119 this time, plus 3.99 shipping.

Sold as Craftsman 3.0 18" that is really 3.4 3400. I took on trade awhile back.

Also tool I made for pulling 026 fly sides works like a charm on these. 1-2 seconds out.

Finally got time to do the seals. Nothing extra needed. No filing bevels in case etc. The SKF goes right in like normal seals.

Start and ran but starving for fuel. Thought needed kit. But just needed cleaned.

Some great info by Tim =  Tim Roberts
The National seals are .001" larger OD than the SKF seals which can be difficult to install. Make sure you build up the area where the step on the crankshaft is on the PTO side or you may turn the seal inside out. I use a piece of 1/2" copper plumbing tube slipped over the crankshaft. The bearings are easy to install but a pain to adjust. They control the crankshaft side play which should be around .010 to .015". You should know that radial play on those drawn cup needle bearings is .005" to .006". They are pretty sloppy. Up / Down play at that value is very easy to feel. It doesn't seem to hurt anything and they rarely wear out.

Doing some 3400 3.7 carbs.  Got a laugh on the red 3.7 one. How you know when it still has original carb kit in it.  😋


Someone has ask about fulcrum height


Just because diaphragms look good don’t mean squat. I had pulled this carb awhile back to clean the fines out from past owner putting fuel filter on wrong line.
Dias felt and looked great. Would run and idle all day. Till you put in wood. It would run out of mix in the cut. New kit in and it don’t do that anymore.

Here is one I a finally getting ready to let go. It was sold as a craftsman 3.0 with 18”.
But is really a craftsman 3.4 poulan 3400 56cc.
Has new fuel and tank vent lines oem echo used. New duckbill. New carb kit. New crank seals.  Finally last piece the dang air filter.
I hide a couple from myself for awhile now.
I ended up putting a 16” set in place of the worn out 18”.
Look at the 358# and you can see how Sears listed this on front cover of manual as a 3.0.
Another air filter I was trying to find turned up too.  🤦‍♂️
