Solo 650 - carburetor replacement option

Hi,
I have a Solo 650 chainsaw with a Walbro 21-245 9-7 carburetor
that I was looking to get an affordable replacement unit from
Amazo to get the saw running. Instead of a rebuild was going to
see if there was a replacement option. Thank you in advance.
Attached is an image of the current carb.

Wonder if a carburetor from a husqvarna 350 chainsaw would work
on the Solo 650?

Havent looked into it before.
But a rebuild kit is less then 10 bucks most times and takes
about 30mins. I'd be digging into that carb first. Just to
simple to rebuild.
Is this the carb? Solo 639 645 650 Chainsaw Walbro HDA126
HDA127A HDA170A = Carb Kit K22-HDA
Solo 650 IPL

I ordered a rebuild kit. I gave the current one a good cleaning
and it seems it's in decent shape. Removed the metering valve
and gave everything a good cleaning. Hard to tell if any ports
clogged. New fuel filter, cleaned carb old gaskets, new
decompression valve, and when I put the spark tester between the
plug I get a decent light pulse. I can see the fuel flow when
the plunger is pressed, just it seems nothing going in the
throttle. I poured a small amount of gas into the throttle blade
port and it seems like it whats to turn over then it dies, does
not last long. Maybe the carb kit will help unless there are
some other ideas. I don't have a compression tester, however,
when the decompression valve is on hard pulls so feels like high
compression. FYI - this is why I thought it would be easier to
try an Amazon carb special that would fit and replace the
original model. Thank you!
