Poulan 3700, worth fixing?

[Pioneer]

Have a 3700 that's missing the air filter cover and filter. Has compression and good spark. Saw is in very good shape showing little visible wear.

I would verify the auto oiler is working first. They have known diaphragm issues before putting money in it. NLA.. Performance wise a very strong saw. Filter is available aftermarket. Cover I might be able to help. If you part it out I may also have some interest. Thx.

I would if it has the chain brake.

 

[Pioneer]

Will have to see if I can get it running.

 

[9050LX]

be surprised if it doesnt run.unless abused.

The 3700 is a very nice saw. Heavier than an equivalent displacement model today but great torque.

Thin rings chrome bore 61cc saw def worth redoing.

 

[Wood Doctor]

I like mine too. Noodle cutting big rounds clogs up more than it should, but it has lots of power for a vintage saw. Always starts and always runs. Worth fixing in my book.

I believe the Echo 590 takes a similar bar and chain also.

So, it runs and quite well. Didn't even have to put a carb kit in it, just drained the brown old gas and it started running once the old gas was flushed out of the carb. Even the mixture needles were spot on. Next to nothing for wear on the rim sprocket either. It pumps oil, but only when the revs pick up, is this normal? The best fitting bar so far is the old one off of my pioneer p40. Anyone know the actual bar mount pattern it is supposed to have? It came with an s type spacer, but the old pioneer bar does not use it.

Id replace the fuel filter and fuel line. They are cheap piece of mind. Great firewood saw!

I remember 8mm bar studs and the D176 bar mount .

A wonderful firewood saw. boatloads of torque.
D176 mount as mentioned. has a thumb operated manual oiler, as well as automatic one. Sounds like your auto oiler is working to some degree. I would run it for awhile, perhaps running a mix of kerosene or diesel and bar oil to help clean out the oiling passages.
The oilers do sometimes quit as the diapraghm becomes less supple ( that saw is about 40 years old).
You can cut out your own diaphragm and replace it.
Very much worth fixing up.

I'd least do tank vent line and new duckbill and fuel line and fuel filter.

Wondering what the fuel line is and where purchased. I have 2 3400's and would like to keep 'em cutting

 

[dboyd351]

appropriate sized tygon works just fine

 

[TLG]

If you would ask @RedneckChainsawRepair what size echo fuel line (4mm?) he is using he would prolly tell ya. If you ask real nice he may even give you the nylon barb and duck bill part numbers to make up a proper vent. Definite must have on these series.

 

[RedneckChainsawRepair]

I use 3x5 echo oem black line on these.

Chris has a shop in PA or can order from his website. Might ask if he will sell to you by the foot. I always buy rolls.
