You will get 1 paper spacer 1/8" and 1 gasket, 2 studs, and 2 nuts to mount your Amal or PWK carb to your classic British bike. Fits years 1967 and up. The studs are  5/16" in diameter.  One side is 22 TPI and the other is 26 TPI. 


You must have the paper spacer to keep engine heat off your carburetor, Your bike originally had a phenolic or Bakelite spacer, many times this is missing and this is why when the bike gets hot it does not run correctly, or it was tuned whilst hot and only runs good when hot. Your bike will never run right without this heat spacer, reason is because the hot carb will heat up the gasoline, gas molecule gets larger and the air to fuel mixture must change.

Modern vehicles still do this with a resin riser, resin intake manifold, any kind of a non conducting material between the throttle body or carb and the engine. Modern vehicles are more forgiving because the computer can change the air/ fuel mixture with mass air sensors on the exhaust and intake, they actually adjust 100s of times each second...... / With your classic motorcycle you have to find a tuning that starts easy and runs good while hot, so there are trade offs with hard jetting, needle height, ignition timing, air valve cut, to achieve this and without a spacer it will be impossible to achieve both. etc
