A really nice addition for your Amal Monobloc float chamber. This float bowl extension will increase the volume of your float chamber, and it is finned to aid cooling of the fuel. This is not supplied with screws, so you will need to have three longer screws to fit.
These float bowl extensions are highly polished, and usually pick up some small marks in transportation and storage. Being aluminium, these should polish out, but please expect some marks.
