I have a Poulan 2300 av that won't keep running. Here's what I've done so far. Checked comp. 90-120 after 4 pulls....good blue spark.....new gas line and filter..line seems good..no kinks or breaks....cleaned carb and rebuilt....piston un-scored...had to replace starter rope and rewind spring...seems to be working fine.....new gas...40:1..full tank......put gas in carb...spits and fires but won't keep running......isn't drawing gas. Have even tried to prime the line....still not drawing gas.....tried adjusting jets between 1-2.5 turns out H and L.....hasn't made it run any better.....ideas, thoughts....all suggestions welcomed....thanks

 

Try without the muffler. It could be restricted.

 

Hi Cheese....thank you...I will try that. I took the muffler and cleaned it really well already but glad to try your idea. Will let you know if it makes any difference.

 

Hi I need the user manual of Poulan Chainsaw 2300 AV.

 

Poulan Chainsaw 2300 AV User's Guide | ManualsOnline.com

 

Is it the same chain saw from your other thread? Now it starts but it won't stay running?

 

HI cheese and everyone out there...this is indeed a different saw. This is a Poulan 2300 av.....not the Poulan 2375 Wild thing I was writing about before. This 2300 av will start when primed...gas is traveling up the new gas line I put in. I tried your suggestion cheese and tried to start it without the muffler on. That was fun...lots of flames, but still only ran till the primer gas was out. I have tried replacing the diaphragms and gaskets but doesn't seem to do the trick. Also according to the manual the h and l jets should b set at 1 turn out then adjusted at 1/16 until it runs. I have tried that too. Is there something else I should be checking? What am I missing on this saw?

 

Hi cheese I read what you wrote about merging the two threads. Is that why I couldn't find the new thread I started saying Poulan 2300 av wont keep running? Is it possible to get that thread restarted? Or do I need to start a new thread. I am new to all of this and want to keep the two threads separate. I appreciate all of your and everyone else suggestions about my poulan wild thing. I am looking at replacing the carb. Thank you all for your input.

 

Okay, sorry, I fixed it for you and put the posts relevant to this saw back in it's own thread. Sorry for the mixup.

 

Does it run better or longer at idle or full throttle? Does applying the choke partially ior quickly on and off help to keep it running longer?

 

Hi cheese....thanks for the reset of my thread...today I tried starting the 2300 av agn....this time it fired when primed....but appeared to fire after the primer had already burned off. But it never runs more than a few seconds. So I took the carb apart and blew it all out...then replaced some gaskets and diaphragms....even changed the spring that holds the needle in side the carb. Now it appears that the gas is not getting drawn to the carb and when I checked the spark plug it is dry. Even tried some gas down the spark plug hole and only got it to fire but still won't keep running. At least this saw tries to run. What am I missing here?

 

It's a fuel issue. Most likely something is wrong in the carb, clogged, etc...

 

Sounds like the cranckcase port to the carb is blocked or a crankshaft gasket is leaking preventing the alternate pressure and vacuum pulses from operating the pump diaphragm. Remove carb and tape a piece of paper over the crankcase port on the carb block. Remove the spark plug. Pull the engine over. You should see the paper move in (vacuum) and out (pressure). If OK, check the carb pump diaphragm. If not OK, use compressed air to blow out the engine crankcase port and check for loose bolts on any crankcase gasketed areas. Also, if the carb has check valves in the idle and high speed ports, the primer will not draw gas from the tank if they are defective.
