dolmar ps34 fuel issues

I have a ps34 that just recently started running extremely rich,
especially on the low end. I have had it for 2yrs and I changed
the carb gaskets when I got it. Has ran great for 2yrs pulling
an 18 " lp bar/chain easily for what I have asked of it. Last
time I went to run it it blew very rich at high idle/wot and
wouldn't idle. I now have the l screw all in/ idle all in and it
still floods out. Do I have a leaky we seal? Pulling the carb on
this saw is a pita so any ideas otherwise would be great...

Sounds like the metering valve diaphragm in the carb is either
stiff or it hasa bunch of sawdust packed into the vent side of
the diaphragm?

That's a possibility. I haven't taken the time to pull the carb
yet. Most saws that I have delt with that had an open metering
valve filled the crankcase with fuel....This hasn't. ... The
problem will probably be obvious once I pull the carb. Thanks
for the ideas
