I especially like this comment by grit Dog
"Just stop taking it places that charge $300 to replace a $30-60 carburetor. "
There are mobile mechanics out there that are ready and willing to work on just about anything.
I would suggest that one seeks out a mechanic in their area and check out their services and cost.
Now, I had my rototiller give me issues after storage even though I had fuel additive in the gas.
A product called mechanic in a bottle was suggested and is available at the big box orange store.
Well, as skeptical as I am i purchased, followed instructions and guess what, it idled smooth as
silk.
