'O' ring for air and throttle screws
Small 'O' ring sealing the air and throttle stop screws on Amal carburetors.
PN · 99-0520 / 622/082
This is the small 'O' ring that seals the air screw and throttle stop screw on Amal carburetors, part number 99-0520 (also seen listed as 622/082). It's a simple rubber seal, but if it's cracked or missing you'll get an air leak right at the screw that throws off your idle mixture no matter how careful you are with adjustment.
