Tao Tao DBX1 150cc Carburetor Replacement

Introduction

If your 150cc Tao Tao DBX1 dirt bike has compression but won't start, the problem is most likely with the carburetor not feeding the engine gas or the manifold not working correctly. A properly maintained carburetor allows for optimal performance, better fuel efficiency, and a healthier engine.

This guide will show you how to replace the carburetor with a new one. Read the instructions carefully and ask a friend or family member for assistance if needed.

Work on your bike in an open garage, outside, or another open area. Before you begin, make sure the bike is off and has cooled down if you recently went on a ride. Have a towel nearby for any gasoline leaks!
