Early 025 air filter. I am starting to have to use sealall to seal off some holes in this guys air filter. 
What was it you use to do the updated set up? The newer black plastic carb intake and filter set up? 
Also any old 025 filters floating around so I can run everything by him for options.

Tank vent I ran over the oem grub screw style.

He likes his old school 025 better then his 251.  Says his 251 delegated to back up.

I have a 025 that wouldnt start.  I replaced the gas line and rebuilt the carb (walbro low and idle adjustment only)  saw fires right up but then dies.  Like it runs out of fuel.  I can gas it and it will run much longer but still will die

Any ideas.?  Maybe my carb is toast ?

025 wouldnt start.  Replaced fuel line and rebuilt carb with kit.  Fired right up 1st pull but wont stay running.  Died in about 3 seconds like it is running out of gas.  Starts easy but dies.  Was able to throttle it to keep it running for a bit but eventually died.

Any suggestions

Has the walbro carb with low speed and idle adjustment only

Carb kit diaphragms gaskets installed in right order.  Screen cleaned or replaced.

Carb L I all set correctly.

Tried new or known good spark plug.

Pulled muffler and checked piston for scuffing.  Checked compression.

Checked impulse line.

No impulse line on my saw.

Gaskets and diaphragm order were verified

I will check out the other stuff you mentioned. 

I'm hoping my dads saw has the same carb and I'm gonna try his carb on my saw

Been a long time since in a 025. But you sure about that.   It is shown right on the 025 IPL

1123 141 8600 - 1 Impulse hose


stihl 025 IPL part # 9 impulse nipple on back of cylinder area. There is part # 19 impulse line tube that runs to back of carb area somewhere. Look for that impulse line.

It may not even be that but you got to check them for cracking, or coming off.   https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2332490.m570.l1313&_nkw=1123+141+8600&_sacat=0

I make my own from 3x6 oem echo line.

I never saw it connected to the handle cover side though. it either came off while I was taking it apart or it wasnt on there.  It was tight on the cyclinder side though. I'm gonna replace it while I have it apart
