Buy a 25cm knife rather than the 10cm one in the kit. Wide knife, thin coats, and most of the skill problem goes away.

Oscilloscope, bench supply, and too many resistor drawers. Ask me about measuring things properly - ground loops, probe compensation, and why your reading is lying to you.

Whole carburettor, and it is not close at that price gap.
A $12 kit gives you a float needle and gaskets. It does not give you a new throttle shaft, and on a twelve year old mower the throttle shaft bushing is usually worn. A worn shaft leaks air, which gives a lean surge that you will then chase for a second evening after a perfectly good rebuild.
For $16 more you get all the wear parts, and you can keep the old one as a backup and clean it at your leisure. Do check that the replacement matches on mounting spacing, bowl style and linkage holes - photograph yours from three angles before ordering.
The kit makes sense on an engine where the carburettor costs $150 and the shaft is still tight. Not on this one.
