There are reputable brands of aftermarket Briggs parts. Stens [US]/Bynorm [Aust] is a very reliable one.

Current diaphragm elastomers should be unaffected by fuels; but from experience we do not recommend the use of any ethanol-containing fuel, in any small engine.

By its very nature [i.e. its aggressive solvent properties for polymeric substances, which includes gums formed from fuel], carburettor cleaner is going to have adverse effects on just about any non-metallic component of a carby.

Some amateur motorcycle mechanics have had very expensive lessons on that one; destruction of nylon carby parts [which can only be replaced by purchasing a complete new or secondhand carby] happens all too quickly!
