FWIW:
I agree with replacing the Walbro, I never liked them.
You might try removing the bowl and cleaning things up a bit, and you may fine it helps or even works ok.
It would only cost your time if you are careful with the bowl gasket/flange gskt.
then you could take a little time to find the carb you want that is adjustable.
Sometimes just a little crud plugs things up.
Luck!

Okay, that sounds like plan A, give the Walbro a cleaning and inspection to see if it will run right. And in the meanwhile, start looking for a #26 (plan b) to have one on hand if/when I decide to bail on the walbro.
