You're lucky the engine block is not made of plastic.
They tried that. Imagine how carefully you'd have to
torque the bolts then. "Oopsy, crack, too much torque"

I've just replaced the plastic carburettor on my Briggs and Straton
engined lawn mower. The third party compatible carb cost around £10
(inclusive of postage). The only metal on the carb is the butterfly
flap, the inlet needle to the float chamber, the pin that is the pivot
point for the float, and the two bolts that hold it together.

I will strip down the one I took off but a can of carb cleaner
recommended for refurbishment could almost be the same cost as the
replacement carb. Also, all gasket kits also seem to be the same price
as a the third party carb replacement - luckily the gaskets are robust
and a replacement is not required for the carb I removed.
