Your model number took me to this link:

I'm just giving you a hint for your review.I seen a Walbro kit 796185 for like $100 and a Nikki carb part number 593432 which you can find for $20 and up.
I always keep my fingers crossed when installing Nikki carbs, especially clones.
What I would
maybe consider doing is order a Nikki from Amazon
(so as can return with free shipping if it don't work) but before I installed the Nikki I would try to clean the Walbro. I've had good luck with making some/most Walbro carbs run W/O a kit just by carefully removing the bowl and cleaning the carb if it has been running OK on the engine and just starting having issues (not setting for long period of time with rust and dried gas inside) or install the Nikki and then clean the Walbro as a spare, but I would not spend $65-100 for a 796185 Walbro kit.
