Minarelli 2T Universal Mikuni-Style Electric Auto Choke

Electric Auto Choke for Minarelli 50cc and Similar Scooters

This electric auto choke suits Minarelli 50cc 2-stroke engines and gives dependable help when starting from cold. It shifts the fuel mix from cold-start to warm-running conditions, which supports steady engine operation. It is one of the simpler Minarelli 50cc / Yamaha jog scooter parts to swap out at home, so it suits a DIY repair. A precision thermal actuator controls fuel flow while the engine is starting.

Construction and Design

The choke uses a precision-machined 7.98mm brass plunger fitted with a rubber boot, which forms a tight seal inside the carburetor's fuel delivery passage. The heat-resistant matte black housing is built to work reliably in a variety of riding conditions. It mounts with a gold/zinc two-tab oval flange, with bolt holes spaced 30mm center-to-center.

Installation and Operation

The choke comes with a 2-pin rectangular female plug on roughly 7 inches of wire. It plugs straight into the factory harness, so no splicing is needed. In its resting open position, it lets extra fuel through during startup. After the engine starts, an internal heater engages and pulls the plunger back to close off fuel delivery as the engine warms.
