The bowls are aluminum and would tolerate methanol if flushed with gasoline before shutdown.
If I remember correctly, H2O2 will destroy aluminum; I would not wish to use it with an aluminum carburetor.
If you are going to run that stuff, then maybe a Zenith 28ADA10 with cast iron bowl would suffice; however, you might wish to consult cousins Frank, Jesse, and Cole for financing options.
