Description

This Universal Parts 15mm velocity stack gives your compatible 33–49cc two-stroke engine a flared carburetor inlet with an integrated manual choke. The compact assembly brings the inlet, choke control and mounting hardware together for an intake replacement or custom off-road setup, with clear dimensions to help you match your carburetor.

Key Features

  • Flared inlet: Funnel-shaped entry leads into the 15mm bore.
  • Integrated manual choke: External lever operates the choke plate for starting.
  • Mounting hardware included: Supplied with two bolts and associated washers.
  • Defined bolt spacing: 30.5mm mounting-hole spacing for comparison with your carburetor.
  • Air-filter mounting surface: 44.7mm outer diameter for a suitably sized filter connection.

Technical Specifications

  • Brand: Universal Parts
  • Part number: 107-47
  • Part type: Velocity stack with choke
  • Bore: 15mm

Compatibility

Fits matching 33–49cc two-stroke engine applications, excluding 47/49cc reed-inducted engines. Compare the 15mm bore, 30.5mm bolt spacing and 44.7mm air-filter mounting diameter with your existing intake and carburetor. Displacement alone does not establish fitment.

Use suitable air filtration and check choke movement and surrounding clearance during installation. Intake changes may require carburetor tuning for your engine setup.

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