Jet block, 25/32 in. choke

Amal carburetor jet block, 25/32 in. choke, listed for the 3TA and 5TA carburetor.

PN · 375/057

This is the jet block out of an Amal carburetor, listed in the parts books as fitting the 25/32 in. choke size. The jet block is the housing inside the carb body that carries the main jet and needle jet, so it's central to how the carb meters fuel at mid-to-high throttle.

Our catalog record ties this one to the CARBURETTER figure for the 3TA and 5TA machines, appearing across 1964 through 1966 listings. If you're rebuilding one of these carbs and the jet block is worn, cracked, or the threads are shot, this is the part number to work from.

If you're not sure your bike's carb takes the 25/32 in. choke version, check the number stamped on your carb body or give us a call before ordering - jet blocks are matched to a specific choke size and body casting.
