Universal Parts 12mm Carburetor - 36-43cc 2-Stroke Scooters

This Universal Parts 12mm Carburetor is a replacement diaphragm-style carb for 36cc to 43cc 2-stroke stand-up and mini gas scooters. It has a 12.5mm venturi, a 31mm two-bolt mounting flange with an O-ring seal, a built-in primer bulb for easier cold starts, brass fuel line fittings, and a throttle cable adjuster, so it's a straightforward swap when your old carb won't idle, starts hard, or runs rough.

This product is intended for off-road use only. This product is not intended for use on public roads or land.
