Mikuni IN HOUSE Tillotson HR Carburetor Conversion Kit with VM30 30mm Carb & Fuel Pump

The Mikuni Tillotson HR Conversion Kit is a comprehensive upgrade solution designed to replace aging Tillotson HR and Walbro WR single diaphragm carburetors on vintage snowmobiles, ATVs, and other two-stroke powered machines. This kit provides everything needed to make the transition from an outdated diaphragm-style carburetor to a modern Mikuni VM30 slide-type carburetor and fuel delivery system.

Kit Includes:

• VM30S 30mm Mikuni Carburetor (Part# VM30S) — smooth-bore slide carburetor for improved throttle response and tunability
• Mounting Flange (Part# LP07467) — adapter flange for installation on original intake manifolds
• Throttle Cable (Part# KX05138) — compatible throttle cable for Mikuni slide operation
• Choke Cable (Part# LP05938) — dedicated choke cable for cold-start enrichment
• Mikuni Fuel Pump (Part# DF44) — pulse-operated mechanical fuel pump for reliable fuel delivery
• Fuel Filter (Part# LP077063) — inline fuel filter for clean fuel supply to the carburetor

Replaces: Tillotson HR and Walbro WR single carburetors

Important Installation Notes:

• This is a universal conversion kit — it is not a direct bolt-on replacement due to the wide variety of machines that originally used Tillotson and Walbro carburetors
• The machine being converted must have an external impulse line to operate the included Mikuni fuel pump
• Custom application work by a qualified technician is required, including: jetting, fuel pump installation, throttle and choke cable routing to controls, and fuel and impulse line installation
• The mounting flange may require drilling to match the stud or bolt pattern of the original Tillotson carburetor mount
• The Mikuni VM-series float carburetor must be installed as close to level as possible; severely angled engine installations may require additional adapters not included in this kit

This kit is the preferred solution for vintage sled and powersports enthusiasts looking to improve reliability, fuel delivery consistency, and long-term tunability by upgrading to proven Mikuni VM carburetion.
