poulan trimmer ?

hello , i have a FL21 weedeater with walbro WA-226 carb it has a
problem with carbon build up and signs of a small flooding problem
smokes a bit with some fuel build up on the frame and spark plug.

i suppose that its an adjustment issue but there is a
resister "the only way i know to put it " that only allows a quarter of
a turn to adjust the high end of the carb. idle can be adjusted as much as
you want .

so my question is what to do to deal with this flooding issue ? its not
enough to make it not run but wastes fuel and run little rough .

things already done :

1:replace complete tank filter and lines

2:new primer bulb

3:new spark plug

4:cleaned carb

5:cleaned muffler of all carbon

6:new air filter

only thing that is not new is carb & engine gaskets .

thx in advance for any reply's .

Sounds like you may have a leaking inlet needle in the carb. New carbs are so cheap that it's not even worth the expense of a kit and the time rebuilding it. I just looked that one up and they are about $40, so not as cheap as many are. You might try leaning the inlet needle and seat, and if that doesn't do, replace the needle and install a kit.

thx for the response , i have another question though it seems that fuel
is getting by the piston and in the bottom of the case and pushing it past
the case seal which is basically throwing it on the plastic of the trimmer .

is fuel supposed to get by the piston or is the case supposed to stay clean
under normal use ? i have seen a lot of older trimmer's that do this same thing .


again thx for your time

The leaking needle is letting gas settle in there and causing problems. Air/fuel mix should enter the crankcase when it's running, but i think your problem is originating from the leaking carb.
