Float chamber

An Amal carburetor float chamber, the housing for the float and needle assembly that meters fuel to the carb.

PN · 19-3143 / 622/050

This is a float chamber for an Amal carburetor, the part that sits alongside the carb body and houses the float and needle assembly that meters fuel into the mixing chamber. It's a fuel-system part, plain and simple, and it shows up in the carburetor plates in our 1972 catalog listings.

The alias number 622/050 is just the Amal-side numbering for the same physical piece as 19-3143 — same part, two ways it's been written down over the years depending on which parts book you're working from.

Our catalog record for this one is thin, just the single entry, so if you're matching this to a specific carb body or bike, bring in your old float chamber or give us a call and we'll get you sorted before you order.
