Eliminate cold-start frustrations with the Universal Parts electric choke (auto-bystarter) for 50cc 2-stroke Minarelli engines. Engineered for Mikuni-style carburetors on 1PE40QMB / 40QMB engines — matte black cylindrical thermal actuator body with gold/zinc two-tab oval mounting flange (30mm center-to-center), brass 7.98mm plunger tip with rubber boot/seal, side-mounted grounding lug, and ~7" black wire leading to a 2-pin rectangular female connector. Plug-and-play replacement: no splicing or soldering required. SKU: 114-77 | MPN: 4746.
Key Features:
- Precision thermal actuator — internal heating element extends brass plunger at the correct rate for smooth cold-to-warm fuel transition
- OEM-spec 7.98mm brass plunger with rubber boot/seal — precision-machined for an airtight seal in the carburetor enrichment circuit
- 2-pin rectangular female connector on ~7" wire — direct plug-in to factory wiring harness, no splicing required
- Gold/zinc two-tab oval mounting flange, 30mm center-to-center bolt spacing
- Heat-resistant matte black housing — consistent operation across all riding temperatures
- SKU: 114-77 | MPN: 4746 | Made in China
How It Works:
This choke is normally open — it allows extra fuel enrichment for starting when no power is applied. Once the engine starts and receives electricity, the heating element warms the wax motor, which slowly retracts the plunger and closes the enrichment circuit as the engine reaches operating temperature. If your scooter runs well for 2 minutes, then starts smoking or fouling plugs, the choke is likely stuck open and needs replacement.
