    Hey y’all, a good friend of mine has this Poulan saw-

    339A4E93-6F51-4147-811A-8B62C5F18A96.jpeg

    He’s owned this saw since ‘96, bought new.
    Recently been a PITA keeping it running. Took it to two shops for fixin’.
    Starts and runs fine, about 15 or so minutes into running, dies out.
    So he’d like to replace the carb with a knock off model. Any suggestions? I’m not much at sourcing such things- I’m hoping someone can chime in.

    brenndatomu ?
    J. Dirt ?
    Mag Craft ?
    Anyone else ?

    Thanks y’all!

    Looks like it is missing a chain brake also.

    I would check into some other things. Like an air leak. Maybe from the intake boot or impulse line or the crank seals. I cut my teeth on those Poulan saws like that .
    They are good saws and worth fixing. Also do the Fuel filter. It can sometimes act that way too. Fuel filter would be the easiest to start with.
    Then you can take the carb off and there is a number on the carb and the make.

    Yeah of it runs that long, it could be a fuel filter that is clogging. It's worth a shot

    Yeah my first thought is that the carb is probably not the problem here...you might also make sure the fuel line in the tank is good...that has been the number 1 thing I have had to replace on my Poulans when they act like you are describing here.

    If it runs perfectly for a few minutes including idle and wide open, I would replace the fuel filter, fuel line, inspect the impulse circuit, and particularly I would remove and clean the tank vent. The coil could also be the issue. I’m thinking the carburetor is probably fine, but they can always use a good cleaning and a carburetor kit.
    Carb should be a Walbro HDA-49
    Carb kit would be K22-HDA

    The carb May be good a place to look.
    I’ve seen the fuel lines on those disintegrate in the tank and get sucked in to the metering valve screen where you’d think it wouldn’t be able to run at all, but does. For a while. Maybe just a good carb clean.

    Yes, I meant to add that last night too...CRS and all. :picard:
    My MS290 acted just like this...run fine for 5-10 minutes, then shut off...no spark until it cooled for a while, rinse and repeat. Coil was bad.

    I have 2 Poulan Pro's that need new few lines right now...run fine with the tank full, as soon as the fuel level gets to a point, it sucks air, runs funny for a minute, shuts off.
    Fuel tank vent not working will do this too, but in this case, adding fuel is the only thing that "cures" the problem...

    Late to the party as usual.....
    :whistle: pretty much what everyone else has said.
    Check the simple stuff first fuel lines and intake boots and such. Look for any air leaks and don’t forget to eliminate coil and plug problems. Carb troubles would seem to give it trouble right off the get go.

    To add....
    My husky 55 I bought brand new and ran for 10 years. Filled it up, dropped and bucked an ash tree. Shut it off for a while and wouldn’t restart.
    Ended up being the original spark plug burned open.

    Just my ¢2. Had many saws do that same thing and 9 times out of 10 it’s a coil that doesn’t short till it’s hot. Good luck don’t give up and you will get it.
