You can find replacement carbs for most engines like this for ~$15 on Ebay.
Whatever is wrong it's likely in the carb. You could take it apart, inspect,
clean. But then you'd need a carb rebuild kit with gaskets, needle valve, etc.
And they cost $5+.

I didn't know that until our discussion here on another thread. I did
exactly that, bought a carb for a Toro Recycler on Amazon this past
summer, about $20 I think. Unbolt the old, bolt on the new,
everything fit, everything was included, it started perfectly and ran
the whole season.

At that price it isn't worth rebuilding. Probably should get a spare.

Now I've collected a couple of non running Ryobi 4 stroke weed
wackers, I think I'll try the same on one of those. Both are missing
fuel lines and the carb looks trashed, one pulls pretty easy and the
other not so much. I've been using corded electrics but this would be
easier if it works.

Battery driven is the way to go.
Especially for a weed whacker.
