Yamaha Carburetor Assy 3 - Fuel Delivery Component - 67C-14903-03-00

Overview

On multi-carb Yamaha setups, each carb has to pull its weight or the whole engine feels off. This assembly plays a big role in keeping fuel delivery balanced, and when one starts acting up, you’ll notice hesitation or uneven power. I’ve swapped these out on engines that just wouldn’t smooth out no matter how much tuning we tried. Once it’s right, the engine runs clean, steady, and responds the way it should.

Key Features

• Balanced Fuel and Air Mixture – Delivers consistent fuel flow for smooth engine operation.
• Genuine Yamaha Fitment – Designed to match factory carburetor specifications precisely.
• Improved Throttle Response – Helps eliminate hesitation and uneven acceleration.
• Supports Engine Consistency – Works with other carburetors to maintain balanced performance.
• Durable Marine Construction – Built to handle vibration, fuel exposure, and harsh conditions.
